PHASE SHIFTED FULL BRIDGE CHARGER CONTROL SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/148201
Kind Code:
A1
Abstract:
A phase shifted full bridge charger control system and a control method, the control system comprising a sampling system and a charger controller, the charger controller comprising: an operation start-up determination unit, a soft-start control unit, an operation control unit and a smooth switching unit, the operation control unit comprising a mode determination unit, a constant voltage control unit, a total current current-limiting control unit and a charging current-limiting control unit. Within a charger operating process, after soft-starting has finished, switching occurs between a constant voltage operation state, a total current current-limiting operation state and a charging current-limiting operation state according to differences in conditions, and the smooth switching unit enables the controller to switch between the operation states according to differences in the charger operation states. The present invention implements smooth transitioning within the charger control method, and has high steady-state performance and dynamic performance.
