application-notes.digchip.comMOSFET Converter Losses 6 2.2 Switching Losses The circuit for the examination of the MOSFET switching losses is presented in fig. 5. It is a single-quadrant chopper supplying an inductive type load. The MOSFET is driven from the driver circuit, providing a voltage U Dr at its output. The MOSFET internal diode is used as a free-wheeling diode ...

fscdn.rohm.comThe switching-losses are calculated in the C and D sections or in the E and F sections of the waveform in Figure 2. When the high-side and low-side MOSFETs are turned ON and OFF alternately, a loss is generated during the transition of the on-switching. Since the equation for calculating the area of the
