Answer to Question 1

Variable voltage inverter (VVI) A variable-voltage inverter (VVI) is basically a six-step,
single-phase or three-phase inverter. The need to vary the amount of voltage to the load became necessary when
these inverter circuits were used in AC variable-frequency motor drives and welding circuits.

Pulse-Width Modulation Inverters. Another method of providing variable-voltage and variable-frequency control for inverters is to use pulse-width modulation (PWM) control. This type of control uses transistors that are turned on and off at a variety of frequencies. This provides a unique waveform that makes multiple square-wave cycles that are turned on and off at specific times to give the overall appearance of a sine wave. The outline of the waveform actually looks very similar to the six-step inverter signal.

Current-Source Input (CSI) Inverters. The current-source input

Answer to Question 2

A
