功率转换电路 meaning in English
power-switch circuit
Examples
- With the development of electronic technology in the field of high - frequency and high - power , power mosfet is gradually enhancing its important status in semiconductor apparatus and is being widely applied in power converters as switch . with the increasing of the operating frequency ( > 200khz ) , the energy loss caused by parasitic capacitance will affect the efficiency of power transforming in converters . especially in the applications of high frequency power supply using mosfet as main devices ( the unit of frequency is mhz ) , the energy loss caused by the switch process will badly affect its efficiency
随着电力电子技术进一步向高频的大功率用电领域发展，功率mosfet在各种电力半导体器件中的重要地位日益显著，使用功率mosfet作为开关器件的功率转换电路也日益增多，但随着器件开关频率的提高(大于200khz ) ，由器件极间电容引起的能量损耗将会影响到功率转换电路的能量传输效率，特别是在以mosfet作为开关器件的高频感应加热电源中(工作频率可达兆赫) ， mosfet在开关过程中的能量损耗严重影响到电源的效率，因此如何减小开关器件的损耗提高高频功率转换线路的效率成为电力电子技术领域的重要研究课题之一。
