Front End Converter, SPWM, PID Controller, SimulinkAbstract
This paper presents the design and simulation of single phase front-end converter in order to improve the
power quality in terms of the power factor and reduces harmonics by implementing a close-loop control method. The
line voltage is also to be boosted using a boost inductor. In all inverter controlled drive applications and in wind power
conversions, the use of two stage power conversion i.e. power conversion from AC-DC and DC-AC is unavoidable.
For such applications this PWM rectifier can be used for primary AC-DC conversion. Sinusoidal pulse width
modulation (SPWM) method has been used to achieve high power factor and to reduce the harmonics. The simulation
results are presented which is carried out with MATLAB/ Simulink.
