Primary Driver
The pc-baord DCDRV is the primary driver board for the transformer. It is a classical half bridge design. The sup-
ply is provided via pins 1, 2 and 3 of the at ribbon cable and the PWM signals (PWM = Pulse Width Modulation)
for driving the MOSFETs are at pin 5 (low side) and pin 6 (high side).
