urn-on and turn-off gate losses. Most of the power is in the MOSFET gate driver. Gatedrive losses are frequency dependent and are also a function of the gate capacitance of the MOSFETs. When turning the MOSFET on and off, the higher the switching frequency, the higher the gate-drive losses. This is another reason why efficiency goes down as the switching frequency goes up.
