ABSTRACT:
A power semiconductor apparatus is provided with power controlling semiconductor modules connected in parallel to each other. Each power controlling semiconductor module controls driving of a power semiconductor device. The power semiconductor apparatus includes a transmission circuit and a reception circuit provided in one and another power controlling semiconductor modules, respectively. The transmission circuit transmits a predetermined communication signal to another power controlling semiconductor module based on a predetermined activation signal generated by one power controlling semiconductor module. The reception circuit receives the transmitted communication signal, and controls driving control operation of another power controlling semiconductor module based on the received communication signal.
