A High Power Density Multilevel Bipolar Active Single-Phase Buffer With Full Capacitor Energy Utilization and Controlled Power Harmonics

Active power decoupling in single-phase conversion systems reduces the required capacitance for twice-line frequency power ripple buffering by operating the energy buffering capacitors with high energy utilization ratios. The bipolar active buffer is the buffer topology that can achieve 100% energy...
