Testing Double Halfbridges and Rectifiers
A special version of our double
halfbridge tester is capable to
provide 100 A forward current
sequentially and up to
6 x 15 A loading current (1 sec
impulse in avalanche, power
control possible) simultaneously
for both halfbridges with selectable voltages for 14 V, 28 V
and 42 V devices.
