Abstract
A novel topology for efficient utilization of parallel inverters as current source active power filter (APF) for high-power applications is presented and analyzed. The proposed technique operates the master inverter with high-power low-switching-frequency devices to compensate the low-order large-amplitude current harmonic components and the slave inverter with low-power high-switching-frequency devices to compensate the high-order small-amplitude current harmonic components. This paper discusses the operating principle, main circuit and control system design. Simulation and experimental results are provided to demonstrate the viability of the scheme.
