Abstract

Conventional converters have a trouble with the high amount of source current harmonics, poor power factor and more ripples. To overcome the above issues, direct parallel connection of two 2-pulse converter has been proposed. Here, Two MOSFET converter circuits are connected in anti parallel with the common DC load. These MOSFET converters are fed from PWM sources, the PWM pulses are generated from the microcontroller. Configuration consists of two MOSFET converters connected back to back. Converter one is operated during positive half cycle (0-90 deg) and the converter two is sustained during negative half cycle (90-180 deg). This strategy accomplishes and yields the desired output signals without ripples and input signal is same for converting time. This converter helps to reduce the source current harmonics and improve the performance factors compared with conventional circuits. There is no additional circuit required for all operating conditions. This converter modifies naturally to guarantee that base consonant execution over the wide voltage range.
