Keywords: Voltage mode Low-frequency oscillation H-bridge inverter Filter-based perturbation control
Abstract: This paper presents a new additional perturbation control method for suppressing low-frequency oscillation in voltage-mode H-bridge DCAC inverter. The stability boundary of the H-bridge inverter is investigated from its small-signal averaged model. High input voltage and light load would cause low-frequency oscillation in this system. To this end, a filter-based perturbation control (FBPC) is proposed for eliminating this oscillation, by using an analog filter to extract the unexpected signal and applying it to the control loop. Theoretical results show a larger stability range of the controlled system with the proposed FBPC. The simulation and experiment results show that the proposed controller can control the low-frequency oscillation in H-bridge DCAC inverter well.
