Single-phase Full-bridge Inverter Design Optimized for DC side Low-frequency Current Ripple
In order to optimize the current ripple on the DC link of single-phase full-bridge inverter, an enhanced single-phase full-bridge inverter and its control strategy are designed to optimize the current ripple on the DC link. At the same time, it provides high quality sinusoidal energy at the AC output. The reinforced full-bridge inverter adds a pair of additional switches and is designed with a complementary control scheme that prevents double-frequency ripple current from flowing into the input of the inverter. The DC input side only provides the DC component of the output power. Finally, the experimental results verify the performance of the designed enhanced single-phase full-bridge inverter.
