Voltage Source Inverter Control of Induction Motor are described here and cycloconverter fed drives. Voltage Source Inverter Control of Induction Motor allows a variable frequency supply to be obtained from a dc supply. Fig. 6.37 (a) shows a VSI employing transistors. Any other self-commutated device can be used instead of a transistor.
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
The electric motor inverter is more than just a power converter — it’s a cornerstone of modern EV design. As shown by Munro Live’s teardown insights and hands-on demos: Six switches and clever control algorithms transform DC into smooth, high-torque AC. Pulse Width Modulation enables precision control and energy efficiency.
The foremost application of inverter control is in controlling the speed of electric motors. By altering the output frequency of the inverter, it’s possible to change the motor’s speed without requiring mechanical gears or pulleys.
