High-efficiency and adaptive input type feedback power system

Abstract

The invention discloses a high-efficiency and adaptive input type feedback power system. The high-efficiency and adaptive input type feedback power system is characterized in that an adaptive grid-connected inversion unit is provided with an output end and an AC input end, wherein the output end is sequentially and electrically connected with an isolation pre-stabilization unit and a boost and buck adjustment unit, an output end of the boost and buck adjustment unit is connected with a measured object, an embedded control unit is electrically connected with the adaptive grid-connected inversion unit, the isolation pre-stabilization unit and the boost and buck adjustment unit and can be used for setting, acquiring and controlling each unit, and a human-machine interaction unit and an external interface unit are electrically connected with the embedded control unit. The system uses a set of circuit to simultaneously achieve functions of a power supply and a load, is small in size and issimple; adaptive single-phase or three-phase AC input and grid-connected output are achieved, manual switching is not needed, and the system adaptability is improved; and seamless power supply and load function switching can be achieved by the same set of closed-loop control, no dead-region voltage does not exist, and moreover, the output accuracy and the response rate are probably improved.

Description

technical field [0001] The invention relates to the field of DC power supply and electronic load equipment, in particular to a high-energy-efficiency self-adaptive input feedback power supply system. Background technique [0002] Various high-precision DC stable power supplies are used in military equipment such as radars, missiles, vehicle-mounted (ship-borne, airborne) equipment, military communications, and measurement control; the development, maintenance, and measurement of power supplies in weaponry and equipment require Various types of electronic loads. [0003] Domestic military scientific research and production units and troops have an urgent demand for high-energy-efficiency self-adaptive input feedback power supply systems. In the past, the conventional DC stabilized power supply and the DC electronic load were two sets of equipment, and the electronic load used a linear scheme and energy-consuming devices. However, there are the following problems when the tw...
