Abstract

A power integration system with motor drive and battery charging and discharging includes a motor (10), a power integration circuit (20), and a battery (30). The motor (10) includes multi-phase paths, and each path has an inductor. The power integration circuit (20) includes an inverter (21) and a charger (22). The inverter (21) includes multi-phase bridge arms, each bridge arm has an upper switch (Q<1>, Q<3>, Q<5>) and a lower switch (Q<2>, Q<4>, Q<6>), and each bridge is correspondingly coupled to each inductor of the motor (10). The charger (22) a switch (SW), the upper switch (Q<1>, Q<3>, Q<5>) and the lower switch (Q<2>, Q<4>, Q<6>) of at least one bridge arm of the shared inverter (21), and the inductor of the shared motor (10). The switch (SW) is coupled between any two bridge arms. The power integration circuit (20) receives a DC power provided by a DC power apparatus (40), and the charger (22) converts the DC power to charge the battery (30), and the battery (30) provides power required to drive the motor (10) through the inverter (21).
