摘要： An apparatus for protecting a device of a motor drive inverter includes a plurality of power modules configured to control the multi-phase alternating current supplied to the motor. Each of the plurality of power modules includes a top phase switching device connected to a positive terminal of the battery, a bottom phase switching device connected in series to the top phase switching device and connected to a negative terminal of the battery, and a current interruption unit connected in series to the top phase switching device and the bottom phase switching device, and configured to be disconnected when a current greater than or equal to a desired interrupting current flows thereto, so as to prevent a switching device of a power module from being burned out due to an overcurrent by installing a fuse wire to the power module.

摘要： An IGBT temperature sense circuit is provided. The IGBT temperature sense circuit automatically calibrates a temperature sense of a diode to minimize an error based on element characteristics of a temperature sense diode, precisely senses the temperature and removes a limit of a maximum current (to increase the maximum current) of an output of an IGBT. A temperature sense circuit includes an automatic calibrator that is configured to supply current of a current source to a current to a diode and a diode temperature sensor that is configured to measure a voltage of one side terminal of the diode based on the current of the diode based on a change of a temperature and adjustment of an operation of a protection object device.

摘要： A system and method for controlling a power module are provided. The system includes a switch element that adjusts output of a power module, a driving signal generation unit that generates a switch ON signal and a switch OFF signal for the switch element, and a latch that is connected between the driving signal generation unit and the switch element and is configured to delay the switch ON signal generated by the driving signal generation unit by a preset delay time and transfer a delayed signal to the switch element. Additionally, a compensation unit is connected between the latch and the power module and is configured to adjust the output of the power module during the delay time by which the latch delays the switch ON signal.

摘要： A circuit for detecting failure of an insulated-gate bipolar transistor (IGBT) power module, is provided to combine failure detecting signals of an IGBT power module using a photo coupler to transmit the isolated signals. The failure detecting circuit includes a circuit that combines six phase isolated failure detecting signals transmitted from a gate drive IC via a photo coupler to be one signal. A plurality of logic gate ICs are omitted, to reduce a material cost, a size of a circuit board, and power consumption.
