MOSFET switching loss與conduction loss計算方式分如下: >switching loss -switch on = 1/2 x Vds x Ids x tp x Fs -switch off = 1/2 x Vds x Ids x tp x Fsw -gate charge loss(Qg) = Vgs x Qg x Fsw -output capacitance loss(Coss) = 1/2 x Coss x V_bulk^2 x Fsw >conduction lo...
► Output capacitance: Coss = Cgd + Cds ► Reverse transfer capacitance: Crss = Cgd 在MOSFET导通之前,首先需要打点这些寄生电容(给输入电容Ciss(Cgd+Cgs)充电,交流模型里D和S“对地”),如图1.7。VGS的驱动电压来临瞬间(上升沿),Ciss(Cgs+Cgd)相当于对地短路,所以峰值的Igs=Vgs/(Rg+r),r为驱动电路...
