A Variable Switching Frequency with Boost Power Factor Correction Converter
Abstract: This paper presents
single phase Power Factor Correction (PFC) with proposed variable switching
frequency (VSF) control technique. The increasing of non linear loads such as
thyristor rectifiers, switching-mode power supplies, adjustable speed drives,
and generate harmonic currents causing various problems to the other equipment
connected to the point of common coupling. There are several disadvantages in
the existing PFC control implementation based on conventional PWM control. This
system considered uses a unified
overcomes such a drawback by converting a voltage source into a fast-acting
current source, which is reduce the harmonics in the line current, increases
the efficiency and capacity of power system.
The capacitor and inductor with voltage and current ripple with minimum
ripple values was designed to absorb sinusoidal input current and to reduce
total harmonic distortion (THD) in the input current with output voltage
regulation. The principal of operation, theoretical analysis, simulation
results on a single phase boost converter are presented.
