Abstract
This paper illustrates the a non-linear demand is applied to a single-phase grid using an active power filter. When a non-linear load is connected to the PCC, harmonics are produced. The single-phase active power filter reduces these harmonics. In order to protect the source from damage caused by harmonic injection, the active power filter is used to divert harmonics produced by the non-linear load. This unique active power filter for a single phase uses a half bridge with shared capacitors. To compensate for harmonics in the source current, the active power filter uses parabolic pulse width modulation (PWM) to regulate the two power electronic components. Source current harmonics are reduced by using the hysteresis controller as opposed to the parabolic PWM. Both controllerscircuits, including the active power filter and the single-phase grid, are modeled in MATLAB Simulink, and time-dependent graphs are produced.
