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.
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 inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.
EV inverters do more than drive the motor — they also enable regenerative braking by reversing the power flow: Instead of pushing current to the motor, the inverter switches on slightly after rotor alignment, generating a drag torque. As the motor spins, it generates AC voltage.
