Does a soft-switching inverter reduce pdiode_Rec?

The application of a soft-switching inverter reduces PMOS_sw and Pdiode_rec. However, it also brings auxiliary circuit losses that mainly consists of the conduction loss of the auxiliary switches Paux_on, the switching loss of the auxiliary switches Paux_sw and the resonant inductor loss PLr.

What is the switching loss in a soft-switching inverter?

The switching loss in a soft-switching inverter consists of the S2 and S3 ZVS turn off loss since soft-switching eliminates the turn on loss. The energy of the ZVS turn off of S3 in Fig. 3 d can be estimated as follows: The energy of the ZVS turn off of S2 in Fig. 3 h can be estimated as follows:

Why is Il (t) bigger in a soft-switching inverter?

It should be noted that iL ( t) in a soft-switching inverter is slightly bigger than that in a hard switching inverter due to the difference in the bridge output voltage uAO ( t) shown in Fig. 6, which causes an increase of PIGBT_on, PMOS_on and PL.
