modelCCM5

Average CCM model with conduction losses and diode reverse recovery

Extends from Interfaces.SwitchNetworkInterface (Interface for the averaged switch network models).

Information

Application: two-switch PWM converters, includes conduction losses due to Ron, VD and diode reverse recovery losses.

Limitations: CCM only, d'>tr/Ts, <i1> > Qr/Ts.

Model taken from EM01 and EMA16.
