Quantifying Incomplete Zero-Voltage Switching Losses Using Equivalent Hard-Switching Losses [PDF]
With fast switching wide band-gap semiconductors conquering high-power application, zerovoltage switching (ZVS) topologies are crucial to increase converter efficiency by minimizing switching losses. However, ZVS criteria cannot always be fulfilled in the entire operating range of the converter. In this case, the converter enters incomplete ZVS (iZVS).

The effect of switching transitions on switched capacitor converters losses [PDF]
2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel, 2012 The contribution of the rise and fall times of switches to the losses of Switched Capacitors Converters was evaluated by an approximate analysis applying the equivalent resistance concept. It was found that switch turn-on and turn-off durations increase the equivalent resistance of the converter and, consequently, the losses, except in the case of ...
