Abstract:The repetitive control and resonant control are widely used in grid-connected voltage-source converters recently, such as uninterruptible power supplies (UPS), photovoltaic inverter (PV) and active power filter (APF). This paper introduces a new repetitive control strategy in APF system, whose repetitive period is only one half of the traditional and could eliminate all odd harmonics as a bank of resonant controllers. Compared to traditional repetitive control, proposed control strategy has faster tracking speed and smaller steady-state error. Compared to traditional PR control, it could be simply implemented in digital processor. Theory analysis with simulations and experiments demonstrate the validity and superiority of proposed fast repetitive control strategy.
