ABSTRACT:The use of electronic equipment used is increasing in the world industry, offices, households and transportation. However, this produces a low power factor value high Total Harmonic Distortion (THD) because equipment, there are components that non-linear (diodes, capacitors, transformers toroids). Therefore, ramp comparison current control needed for boost converter electric system to ...

Due to the rapid growth of non-linear loads, such as power electronic control equipments and Electric arc furnace (EAF) power quality problems such as harmonics and voltage flicker are introduced in the power system. It occurs because of the time-varying and nonlinear behaviour of the Load. Arc furnaces are used in industries for induction heating and welding. Hence an Electric arc furnace mode...

A novel rectifier topology for high power (0.5 to 10 MVA) current source based ac motor drives is proposed. This rectifier is composed of a multi-winding transformer, a multi-level diode rectifier and a modified multi-level buck converter. The rectifier produces near unity input power factor and sinusoidal input current under any operating conditions. In addition, the proposed rectifier feature...

Voltage and current source inverter are widely used in electrical motor drives. In this drives, DC voltage (or current) are usually provided from phase control or line commutation rectifiers. Because of disadvantage & limitation of this converter, some new topologies are presented in advanced drive such as PWM rectifier.
