Inverter mother board is the host board in inverter module. It consists of a 3-phase SiC inverter module rated at 1200V/ 50A, a heat-sink and a blower fan for thermal dissipation. Certain functions of the inverter module are realized on separate daughter cards or sub modules that would plug into inverter mother board. This helps with easy debugging and to easily replace modules in case of error or if improvements are needed. It has various connectors to connect to the control module and various sub modules. Besides it has appropriate PCB terminations for mounting high power lugs to feed in high power DC and to draw high power inverter output to motor. Here below is the list of modules it supports
The inverter mother board is shown in Figure 3-21.
The inverter mother board is fabricated with 2-oz copper on either side and high current traces / planes are parallel routed on either sides to give a 4oz effective thickness. Its connectors J17, J21 and J22 will mate with control mother board headers J3, J4 and J6 to receive control signals and send feedback signals.
