Abstract
An extensive analysis on the switching frequency to the performance of shunt active power filter (SAPF) was made. A first-order inertia element was considered as the approximate model of SAPF. The compensation characteristic for each order harmonic current was obtained at different switching frequencies. With two types of system loads which were rectifier with resistance and inductance load and rectifier with resistance, inductance and capacitance load, the THDs of source current after compensation were presented with different switching frequencies by using figures. The compensation characteristics for the most widely used digital control system were investigated. Based on these analyses, the specification of compensation characteristics with different switching frequencies is quite straightforward.
