Keywords: MOSFET switch, Single-phase switch mode ac-dc converters INTRODUCTION:Improvements in power factor and total harmonic distortion can be achieved by modifying the input stage of the diode rectifier filter capacitor circuit. Passive solutions can be used to achieve this obj...
Power Factor Improvement with SinglePhase Diode Rectifier in Interior PermanentMagnet Motor The variable-speed ac motor drive systems used in home electrical appliances are required to have power factor correction circuits. The primary goal is to achieve the reduction of harmonic contamination in the so...
This paper focuses on the power quality improvement of three phase diode rectifier for DC drive applications. The input current harmonics distortion (THD), power factor at input side and voltage regulation of the three phase diode rectifier is investigated for power quality improvement. In this meth...
So, the transformer size, weight and stress factor are reduced considerably [3]. This converter does not provide any benefits in terms of control or power-factor improvement, and may not protect the critical loads from the instantaneous power interruptions due to lack of energy storage system. ...
