摘要

An intelligent power module having a snubber capacitor for surge reduction installed therein is disclosed. IPM having a snubber capacitor according to an embodiment of the present invention can prevent a device from malfunctioning or being destroyed by a surge voltage. An embodiment of the present invention can allow for easy design of the IPM and reduction of an area and cost of a PCB

主权项

1. An intelligent power module having a snubber capacitor for surge reduction installed therein, comprising:
a drive IC configured to receive a first voltage signal from a micro controller unit and generate a second voltage signal; a switch configured to receive the second voltage signal from the drive IC and generate a motor driving signal for driving a motor based on the second voltage signal; and a surge reducer connected in between the switch and the motor and configured to reduce a surge voltage.
