A high integrated semiconductor module for a switched reluctance motor is provided to enhance the reliability of an element by incorporating overcurrent and low voltage protection functions, and a thermistor capable of monitoring temperature of the module in the semiconductor module. A high integrated semiconductor module(300) for a switched reluctance motor includes a first switching element(321), a high-voltage integrated circuit(310H), a second switching element(322), a low-voltage integrated circuit(310L), and first and second diodes(331,332). The first switching element is configured to allow a driving current to flow on one input terminal of the switched reluctance motor. The high-voltage integrated circuit controls a switching operation of the first switching element. The second switching element is configured allow the driving current to be extracted from the other input terminal of the switched reluctance motor. The low-voltage integrated circuit controls a switching operation of the second switching element. When the first and second switching elements are turned off, the first and second diodes for feeding back the current is integrated in one semiconductor package. |
