An exhaustive literature survey is carried out in following broad areas of the PWM techniques converter.

PWM advantages such as low current distortion, controllable DC voltage level, controllable power factor and regenerative capabilities are demonstrated.

Sinusoidal Pulse Width Modulation (SPWM) and Sinusoidal Vector Pulse Width Modulation (SVPWM) modulation strategies are compared.

It is, therefore, essential to predict the harmonic levels that these converters produce.

In their paper, a fast time domain method is presented to solve for the current and voltage harmonics injected by single-phase diode bridge rectifiers.

The circuit is composed by two three-phase 6-pulse rectifiers in parallel connected by four balancing reactors.

One is a conventional thyristor rectifier with a lag firing angle (α).

Inner loop current controllers Outer loop voltage controllers Various standards are set to limit the harmonics generated by use of power electronic devices and non-linear loads. It gave the first guidelines for system harmonics limitations and revised in 1992 [193].

The 5% voltage distortion limit was recommended below 69 k V, while the limit on current distortion is fixed in the range of 2.5% to 20% depending upon the size of the customer and the system voltage.

In half-wave converter, topology has half the number of switches of the full-wave topology.

The half-wave topology can deliver power only for motoring in both the directions without regenerative capability.

Implementation of voltage orientation control is complicated. [69] have analyzed and predicted that current control with a fixed switching frequency has a fast dynamic response, ease of control and good switching pattern.
