具有高开关频率和固有PFC能力的谐振无桥AC/DC整流器

Boost-based converters are used in a variety of nonisolated step-up applications, such as power factor correctors, because of their simplicity. The power density of these converters can be increased in higher switching frequencies, which reduces the size of the magnetic elements. This increases the switching losses, but that can be solved by soft-switching techniques. This paper proposes a resonan...
