MOSFETs Two-Switch Forward Converter: Operation, FOM, …

The second switching loss is that associated with charging and discharging of the MOSFET output capacitance Coss. In ATX power supplies, the popular two-switch forward converter follows the PFC converte r having an input voltag e ~400 V. As a result, the output switching loss can be a significant portion of the total losses.
