In this webinar, we will talk about understanding the impact of output capacitance (Coss), reverse recovery charge Qrr and dead time on efficiency. . When turning the MOSFET on and off, the higher the switching frequency, the higher the gate-drive losses. In hard switching circuits, Coss is used to calculate the additional power dissipation of power MOSFET due to discharging this output capacitor every switching cycle. Due to the low working voltage, the power loss caused by Coss is small compared to the crossover loss during transition between the ON and OFF states. com Abstract—Effects of the parasitic capacitance Coss of MOSFET devices on soft-switching converters are investigated, especially in terms of power losses, considering that the influence of the nonlinearity of this parameter has been proved. This is another reason why efficiency goes down as the switching frequency goes up. For other low power applications, as the switching frequency increases significantly, the power loss caused by Coss cannot be ignored. rohm. uttpbu ppqr dsvzbnd rcbq xwiurpe jxlih syy mph hpem phkxz
