Title:
POWER SOURCE INTEGRATION SYSTEM WITH MOTOR DRIVING FUNCTION AND BATTERY CHARGING AND DISCHARGING FUNCTION
Document Type and Number:
Japanese Patent JP2023070186
Kind Code:
A
Abstract:
To provide a power source integration system with a motor driving function and a battery charging and discharging function.SOLUTION: A power source integration system with a motor driving function and a battery charging and discharging function includes a motor, a power source integration circuit, and a battery connected to the power source integration circuit. The power source integration circuit has a multiphase bridge arm. The bridge arm of each phase includes an upper switch and a lower switch. The bridge arm of each phase includes an inverter connected to a coil of each phase of the motor, and a charger including a charging unit. The charger and the inverter share the upper switch and the lower switch of the bridge arm of at least one phase of the multiphase bridge arm. The power source integration circuit receives DC power source supplied from a DC power source device. The charger charges the battery by converting the DC power source. The battery supplies power necessary to drive the motor through the inverter.SELECTED DRAWING: Figure 1
