High efficiency and low input current distortion Totem-Pole Bridgeless PFC

As time progresses and technology develops in recent years, the demand for networking communication products is on the increase. Almost all nations throughout the world adopt AC power transmission system. To avoid current phase shift or distortion that would indirectly influence energy conversion performance and power quality in the AC-DC conversion process, it's important to insert PFC into power supplies. A PFC is to change the waveform of current drawn by a load to improve the power factor, reduce input current spike and control the harmonic current. This proposal aimed to design and implement a high efficiency, high power factor, high power density and low input current harmonic PFC. Due to the fast switching property of Wide Bandgap (WBG) Power Semiconductor Devices, it can reduce the loss and improve conversion efficiency, therefore increase the total power density.
