Title:
電力用半導体装置
Document Type and Number:
Japanese Patent JP4336214
Kind Code:
B2
Abstract:
Inverter circuits are connected to a P electrode and an N electrode, and control the U, V and W phases, respectively, of a three-phase motor. The inverter circuits are connected to the three-phase motor through shunt resistors, respectively. The shunt resistors are connected to HVICs, respectively. The HVICs are connected to a counter circuit. The counter circuit is connected to a CPU. The CPU is connected to a clock transmitter and a gate drive circuit.
