Pulse Width Modulation

Pulse width modulation (PWM) drives, like the Siemens
MICROMASTER and MASTERDRIVE VC, provide a more
sinusoidal current output to control frequency and voltage
supplied to an AC motor. PWM drives are more efficient and
typically provide higher levels of performance. A basic PWM
drive consists of a converter, DC link, control logic, and an
inverter.
