In case one of the four diodes shows a short circuit or an interruption, the rectifier is defective
and has to be exchanged.

4.8.2

Transistor module (IGBT)

The IGBT (

I

nsulated

G

ate

B

ipolar

T

ransistor) is fixed on the circuit board with three solder

connections.

The IGBT Transistor has as a supplementary protection an integrated recovery diode. At first,
we have to measure the on-state voltage of this diode. The forward voltage of this diode
should be about

0,5V

.

In case the recovery diode shows a short circuit or an interruption, the IGBT transistor
is defective and has to be exchanged.
