Filter impact based on inverter circuit performances

This paper examines filter component impact on inverter output. The inverter prototype was designed by using pulse width modulation (PWM) signal generated by EGS002 module, combined with DC voltage source, voltage regulator, MOSFET Bridge and low pass filter. As component assembled, the output voltage quality is determined by the choice of filter components. Experiment shows that the calculated values may not suitable as soldering and connection imperfection may change component values. As adjustments were performed, filter components of 12.63 H and 6.5uf generated the finest sinusoidal output of 30.8 Vpp with frequency of 50.05 Hz.
