The invention provides a programmable DC power supply implementation system and method, and the system comprises a rectifier, an inverter, a feedback switch, and a main controller. Moreover, the feedback switch is used for connecting the output end of the inverter to an AC power grid, and connecting a DC bus between the rectifier and the inverter to a DC output end. The main controller comprises a parameter receiving unit and a mode control unit, wherein the parameter receiving unit is used for receiving working parameters inputted from the outside. The model control unit is used for controlling the operation states of the feedback switch, the rectifier and the inverter according to the received working parameters, and enables a DC power supply to work in a storage battery simulator mode, a feedback type DC load mode or a unidirectional DC power supply mode. The system enables a plurality of functions to be integrated in the same set of equipment, switches the working mode of the DC power supply according to the working parameters inputted from the outside, can meet the integrated demands of development and research, production and testing, and saves the cost.
Description
technical field [0001] The present invention relates to the field of DC power supply, and more specifically, to a system and method for implementing a programmable DC power supply. Background technique [0002] In order to ensure the safe and stable operation of DC power supplies such as batteries, it is necessary to test various parameters of these power supplies. However, when testing the power supply entity, unsafe accidents sometimes occur, so the simulator is often used instead of the real power supply to apply to the early stage of equipment debugging, testing, and joint testing. At present, some battery test systems have appeared in the field of DC power supply control at home and abroad, such as the battery test system of Digatron (Germany), and the high-precision photovoltaic battery simulator power supply of Regatron (Switzerland). [0003] However, the existing DC power supply control systems generally have the problem of realizing a single function. For example...
