Types of Variable Frequency Drive

Voltage-source inverter drives

Voltage-source inverter (VSI) drives are the most common variable frequency drives in the market. They consist of a rectifier that converts AC to DC, a DC link, and an inverter that converts DC back to AC. The inverter section uses pulse width modulation (PWM) to control the frequency and voltage applied to the motor, resulting in precise control of the motor's speed and torque.

Current-source inverter drives

Current-source inverter (CSI) drives are the second of the three basic types of variable frequency drives. These drives employ a rectifier, a DC link, and an inverter. They also use field-effect transistors (FETs) that have a higher switching speed than the insulated-gate bipolar transistors (IGBTs) in VSI drives. This feature enables CSI drives to accommodate high-speed applications and yield faster dynamic responses.

Direct torque control drives

Direct torque control (DTC) drives offer the highest level of control among the variable frequency drives. DTC technology monitors and controls motor torque and flux directly instead of operating through an intermediate variable frequency control stage. The result is increased accuracy, minimized torque ripple, and faster dynamic responses.

Variable Frequency Drive Key Features

Continuous run current rating

This is the maximum rms current the variable frequency drive can safely handle under all operating conditions at a fixed ambient temperature (usually 40 [degrees] C). Motor ball load sine wave currents must be equal to or less than this rating.

Overload current rating

This is an inverse time/current rating that is the maximum current the variable frequency drive can produce for a given time frame. Typical ratings are 110% to 150% overcurrent for 1 min, depending on the manufacturer. Higher current ratings can be obtained by oversizing the variable frequency drive. This rating is very important when sizing the variable frequency drive for the currents needed by the motor for break-away torque.

Line voltage

As with any motor controller, an operating voltage must be specified. Variable frequency drives are designed to operate at some nominal voltage such as 240VAC or 480VAC, with an allowable voltage variation of plus or minus 10%. Most motor starters will operate beyond this 10% variation, but variable frequency drives will not and will go into a protective trip. A recorded voltage reading of line power deviations is highly recommended for each application.

Applications of Variable Frequency Drives

Swimming pool filtration systems
Variable frequency drives can be used in indoor swimming pool filtration systems to increase cleanliness. variable frequency drives used in indoor swimming pool filtration systems can help to lower the electricity consumption by easily varying the water volume as required. 40% of the power used by swimming pools is needed to filter the water. A pump using a variable frequency drive can aid in the recycling of water by drawing it into the filtration system.

Pressure booster pumps
Commercial or large buildings like hotels require sufficient high water pressure to reach all units, including bathrooms and showers, using a pressure booster pump. variable frequency drives can be a better alternative to pressure control valves since they have better energy savings and eliminates maintenance costs.

HVAC systems
Variable frequency drives have been used in HVAC systems for decades. Traditionally they have been used for capacity modulation, but in recent years they have also been used for fan and pump balancing, equipment monitoring, and cutting equipment energy usage at peak load conditions. variable frequency drives can help reduce the wearing of components of HVAC systems, as they require less energy to start a motor, thus reducing the components stress.

Variable Frequency Drive Safety Instructions

Ensure Each Variable Frequency Drive Is Engineered Properly
A properly sized variable frequency drive can effectively handle the required torque in any situation.

Schedule Professional Installation
Professional installation is crucial.
Installation that meets electrical regulations.
Correctly mounted drives.
Properly grounded and bonded wiring.
Installation that facilitates adequate airflow.
Properly reinstalled protective covers and barriers.

Inspect Variable Frequency Drives for Potential Complications
You should regularly inspect your stored and operating variable frequency drive to ensure no complications are present. For example, forklifts or other equipment may bump a stored or operating variable frequency drive, causing potential damage, or a stored variable frequency drive may lack important components if an employee used a stored component to repair an operating variable frequency drive.

Regularly Maintain the Variable Frequency Drive's Components
Variable frequency drives last longer and remain in good condition when you maintain them properly. Check your variable frequency drive's manual for recommended maintenance intervals, and plan equipment downtime. Thoroughly inspect and clean your variable frequency drive to detect any potential complications and remove objects that may prevent heat dissipation.

Use the Correct Motor
Variable frequency drives generate pulse-width modulation (PWM) waveforms to produce synthetic AC waveforms. PWM waveforms can cause high voltages, but a proper variable frequency drive motor can handle high voltages and protect the variable frequency drive's components from damage.

Train Personnel
Train your equipment operators and maintenance staff on how to operate and protect variable frequency drives properly. Employees who work with or maintain variable frequency drives should understand how they operate so they can identify abnormalities and schedule maintenance or repairs when necessary.

FAQ

Q: How do you size a variable frequency drive?

A: Sizing of a variable frequency drive is based on the rating of the variable frequency drive and the motor load. When the variable frequency drive is rated in horsepower (or in horsepower and output current), the variable frequency drive must be sized to be greater than or equal to the horsepower rating of the motor (or motors).

Q: What are the standards for variable frequency drive?

A: All variable frequency drives must have an adjustable carrier frequency range of 750 Hz to 15 kHz. 12. All variable frequency drives must be equipped with AUTO restart for instances in which the power system returns to normal after a power line transient (overcurrent, overvoltage, or undervoltage) or outage.

Q: How do you match a variable frequency drive to a motor?

A: The voltage rating of the variable frequency drive must match the motor/facility's power supply (e.g., in the USA, 230 V class or 460V class, in Canada, 230V, 460V, or 575V). The nominal current rating (in amperes) of the variable frequency drive must be equal to or greater than the motor's current rating.

Q: What is a variable frequency drive?

A: Variable frequency drive, also known as an adjustable frequency drive or an inverter, changes the frequency and voltage supplied to an electric motor. This feature optimizes the speed, torque, and performance of a motor, ultimately leading to energy efficiency.

Q: Why variable frequency drive is used?

A: Variable frequency drive can vary the power supplied to match the energy requirement of the driven equipment, and this is how it saves energy or optimizes energy consumption.

Q: When to use a variable frequency drive?

A: The application you're running requires precise control.
Your application contains a variable load.
Your application involves regular starting and stopping, as is the case with some conveyor applications.
Your motor is running at full speed with throttled output.

Q: How do variable frequency drives work?

A: Variable frequency drive's are used to control ac motors. The variable frequency drive's input voltage (ac power supply) is reduced by the variable frequency drive transformer, rectified and filtered into dc voltage. The variable frequency drive then converts the dc voltage into adjustable frequency ac output voltage that matches the speed of the motor to be controlled. Proportional speed control is achieved by varying the variable frequency drive output frequency.

Q: What are the control methods of a variable frequency drive?

A: The most common technique for controlling the speed of a variable frequency drive is to use a feedback signal from the motor to the variable frequency drive. The variable frequency drive then adjusts the frequency of the power supplied to the motor to maintain the desired speed.
