3.7 Control BoardThe control board monitors the circuits. In case of a supply voltage gap, an occurring overheat at the temperature sensors or a high ohmic value at IN_3_low, IN_4_low or In_5_low the digital signal generator is disabled and the H - Bridge - IGBTs are non-conducting.

Figure 3.38: Protel Schematic: Control Board IN_3_low, IN_4_low or In_5_low can be used to activate/deactivate the voltage multiplier. When not in use they have to be short-circuited. Figure 3.39 Figure 3.40 show the mounted and tested PCB.
