4.0 Reverse Recovery Loss

The following procedure is recommended for use where it is necessary to include reverse recovery loss.

From waveforms of recovery current obtained from a high frequency shunt (see Note 1) and reverse

voltage present during recovery, an instantaneous reverse recovery loss waveform must be constructed.

Let the area under this waveform be E joules per pulse. A new sink temperature can then be evaluated

from:

T_K= T_{j(MAX )}− E ⋅

[

k + f ⋅ R_thJK

]

Where k = 0.2314 (°C/W)/s

E = Area under reverse loss waveform per pulse in joules (W.s.)

f = Rated frequency in Hz at the original sink temperature.

R_thJK= d.c. thermal resistance (°C/W)

The total dissipation is now given by:

W_(tot)= W_{(original )}+ E ⋅ f

NOTE 1 - Reverse Recovery Loss by Measurement

This device has a low reverse recovered charge and peak reverse recovery current. When measuring the

charge, care must be taken to ensure that:

(a) AC coupled devices such as current transformers are not affected by prior passage of high

amplitude forward current.

(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring oscilloscope

to avoid overloading the internal amplifiers by the relatively high amplitude forward current signal.

damped snubber, connected across diode anode to cathode. The formula used for the calculation of this

snubber is shown below:

Where: V_r= Commutating source voltage

C_S= Snubber capacitance

R = Snubber resistance
