摘要

在设计传统的开关变换器时,由于较高的开关应力和开关损耗,提高工作频率以减轻磁性和滤波元件的重量、尺寸和成本的努力一直受到阻碍。为了克服这些障碍,提出了谐振开关的概念。通过合并额外的Land C元件来塑造器件电流和电压波形,可以实现所需的零电流开关特性,从而使变换器能够在兆赫范围内工作。

Resonant switches - Topologies and characteristics
In designing conventional switching converters, the effort to increase operating frequency in order to reduce weight, size and cost of magnetic and filter elements is constantly hampered by higher switching stresses and switching losses. To overcome these obstacles, the concept of resonant switch was proposed. By incorporating additional Land C elements to shape device current and voltage waveforms, the desired zero-current switching property can be realized which enables converters to operate in the megahertz range.
