【正文】 itches conduct heavy current and have nonzero voltage across the switch in the onstate power losses are given by Pon=Uson ，并且在通態(tài)時(shí)有非零的壓降。 Switching losses 開關(guān)損耗 Power losses in the power eletronic converters are prised of the Switching losses and parasitic losses. 電力電子轉(zhuǎn)換器的功率損耗分為開關(guān)損耗和寄生損耗 the parasitic losses account for the losses due to the winding resistances of the inductors and transformers,the dielectric losses of capacitors,the eddy and the hysteresis losses. 寄生損失的繞組電感器、變壓器的阻力、介電損耗的電容器 ,渦流和磁滯損耗 the switching losses are significant and can be managed. 這個(gè)開關(guān)損耗是非常重要的 ,可以被處理。Semiconductor switches are very important and crucial ponents in power electronic switches are meant to be the substitutions of the mechanical switches,but they are severely limited by the properties of the semiconductor materials and process of manufacturing. 在電力電子系統(tǒng)，中半導(dǎo)體開關(guān)是非常重要和關(guān)鍵部件。半導(dǎo)體開關(guān)將要替換機(jī)械開關(guān) ,但半導(dǎo)體材料的性質(zhì)和生產(chǎn)過(guò)程嚴(yán)重限制了他們。 they can be further divided into three ponents:(a)the onstate losses,(b)the offstate losses and the losses in the transition states. 他們可以分為三個(gè)部分 : 通 態(tài) 損耗，斷 態(tài) 損耗 和轉(zhuǎn)換過(guò)程中產(chǎn)生的損耗。這個(gè)通態(tài)功率損耗的公式為 Pon=Uson if. The Uson and If are respectively the switch voltage in the onstate and the forward current through the example,the typica
