Fig.1. Definition of t

rr, Qs and Irrm

Fig.2. Definition of V

Fig.3. Maximum forward dissipation P

F = f(IF(AV)) per

diode; square wave where I

F(AV) =IF(RMS) x √D.

Fig.4. Maximum forward dissipation P

F = f(IF(AV)) per

diode; sinusoidal current waveform where a = form

factor = I

F(RMS) / IF(AV).
