The signals before PWM and after PWM are shown in Figure 2 and Figure 3 respectively. Compared with Figure 2, the frequency of the signal in Figure 3 is increased, the amplitude remains unchanged and therefore the average value of the signal is decreased.

Therefore PWM just meets the requirement of VVVF described in section and is adopted. This research work investigates the various applications of a PWM rectifier based on its input power factor.

Most of the cases, the papers describe the operation of the rectifier used for unity power factor (UPF) operation. Beside this mode of operation, this paper compiles the application of the rectifier as STATCOM also, where the rectifier deals only with reactive power Author: Arkendu Mitra, Sumana Chowdhuri.

Three-phase controlled rectifiers have a wide range of applications, from small rectifiers to large high voltage direct current (HVDC) transmission systems.

They can be categorized into line-commutated controlled rectifiers and force-commutated pulse width modulated (PWM) rectifiers. The current regulator in the rectifier controller block generates three-level signals (-1, 0, 1), indicating if the average-value PWM rectifier model is supplied by a negative, zero, or positive line voltage (Vab and Vbc).

In detailed mode, the rectifier controller block outputs the actual pulses for the rectifier switches. pulse width modulation (PWM) boost type rectifier when operating under different supply voltage conditions (balanced, unbalanced, and distorted three-phase supply voltages).
