Title:
INVERTER CONTROL BOARD
Document Type and Number:
Japanese Patent JP2017060255
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a smaller inverter control board by appropriately arranging a low voltage circuit such as a control device that has comparatively low voltage and a high voltage circuit such as a drive circuit that has a comparatively high voltage.SOLUTION: An inverter control board 10 has a low voltage circuit area LV and a high voltage circuit area HV. The high voltage circuit area HV has a plurality of drive circuits D and a second AC machine control circuit 12. The low voltage circuit area LV has a power control circuit 15 that controls switching power source S that supplies power to the drive circuits D and second AC machine control circuit 12, and a first AC machine control circuit 11. The high voltage circuit area HV is divided into a first high voltage circuit area HV1 on the upper side and a second high voltage circuit area HV2 on the lower side. The low voltage circuit area LV is formed between the first high voltage circuit area HV1 and the second high voltage circuit area HV2, and the second AC machine control circuit 12 is disposed in the second high voltage circuit area HV2.SELECTED DRAWING: Figure 8
