開關(guān)電源的工作過程相當(dāng)容易理解，在線性電源中，讓功率晶體管工作在線性模式，與線性電源不同的是，PWM開關(guān)電源是讓功率晶體管工作在導(dǎo)通和關(guān)斷的狀態(tài)，在這兩種狀態(tài)中，加在功率晶體管上的伏-安乘積是很小的（在導(dǎo)通時(shí)，電壓低，電流大；關(guān)斷時(shí)，電壓高，電流小）/功率器件上的伏安乘積就是功率半導(dǎo)體器件上所產(chǎn)生的損耗。
　　與線性電源相比，PWM開關(guān)電源更為有效的工作過程是通過“斬波"，即把輸入的直流電壓斬成幅值等于輸入電壓幅值的脈沖電壓來實(shí)現(xiàn)的。 脈沖的占空比由開關(guān)電源的控制器來調(diào)節(jié)。一旦輸入電壓被斬成交流方波，其幅值就可以通過變壓器來升高或降低。通過增加變壓器的二次繞組數(shù)就可以增加輸出的電壓值。zui后這些交流波形經(jīng)過整流濾波后就得到直流輸出電壓。
