Abstract
An intelligent power module (IPM) is formed of an inverter having power elements, a predriver for driving the inverter, and a protect circuit, and all these components are integrated into the same package. A shunt resistor is provided at an output of the inverter so that an end-to-end voltage of the shunt resistor can be output to an external device. This configuration enables an output current from an inverter apparatus incorporating the IPM to be detected without using a current transformer that requires a large installation space. In addition, the module terminals of the IPM and the terminal blocks of the inverter apparatus are integrated together to eliminate the need for wire rods and set screws for connections which are used to connect the module terminals and the terminal blocks together.
