Title:
MULTI-FUNCTIONAL INTEGRATED CONTROLLER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/047001
Kind Code:
A1
Abstract:
A multi-functional integrated controller circuit, wherein: a power grid (101) is connected to a first terminal of a power factor correction PFC circuit (102), while a second terminal of the power factor correction PFC circuit (102) is connected to a first terminal of a primary circuit (103) of a direct current conversion circuit; a second terminal of the primary circuit (103) of the direct current conversion circuit is connected to a primary winding of a transformer (104), and a first secondary winding of the transformer (104) is connected to a first terminal of a first secondary circuit (105) of the direct current conversion circuit, while a second terminal of the first secondary circuit (105) of the direct current conversion circuit is connected to a power battery (106); a second secondary winding of the transformer (104) is connected to a first terminal of a second secondary circuit (107) of the direct current conversion circuit, and a second terminal of the second secondary circuit (107) of the direct current conversion circuit is connected to a first terminal of a step-down circuit (108), while a second terminal of the step-down circuit (108) is connected to a first terminal of a low voltage battery, a second terminal of the low voltage battery (109) being connected to a vehicle-mounted electronic device (110) and a battery management system (BMS) (111) respectively. The multi-functional integrated controller circuit integrates a charging circuit and a driving circuit of a new energy vehicle, said two circuits sharing components so as to reduce components and reduce costs.
