Embodiment Construction

[0047] In the following, the invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0048] refer to figure 1 , is a schematic diagram of the main structure of a series of adjustable parameter converters according to an embodiment of the present invention.

[0049] exist figure 1In , it is shown that the converter includes an input control stage, an isolation control stage, an inverter control stage and an output feedback stage.

[0050] The input control stage, the isolation control stage, and the inverter control stage are connected in sequence, and the output of the previous stage is used as the input of the subsequent stage; the output of the inverter control stage is used as the output of the converter and connected to the load network, At the same time, it is sent as a feedback signal to the output feedback stage, and the output feedback stage generates a feedback signal and sends it to the input control stage.

Abstract

The invention provides a series-parameter-adjustable converter and power supply assembly used for the converter. The converter comprises an input control stage, an isolation control stage, an inversion control stage and an output feedback stage. The input control stage comprises a plurality of high-voltage rectifying circuits which are connected in parallel; the isolation control stage comprises a DC-DC conversion circuit and an isolation protection circuit connected with the DC-DC conversion circuit. the inversion control stage comprises a plurality of inversion controllers; an input control parameter is determined based on an AC network parameter input by the input control stage; an isolation control parameter is adjusted based on an output signal of the input control stage; and the inversion control parameter isadjusted based on an feedback signal and the isolation control parameter. The invention also provides a power supply assembly for the converter. The power supply assembly comprises a reference source, a protection unit and a feedback unit. The feedback unit constitutes the output feedback stage of the converter. The reference source forms the reference source circuit of the converter. According to the series-parameter-adjustable converter and the power supply assembly used for the converter of the invention, multi-stage parameter controllable adjustment of the converter is realized.

Description

technical field [0001] The invention belongs to the technical field of converter circuits, in particular to a converter with adjustable series parameters and a power supply assembly thereof. Background technique [0002] In terms of energy supply and conversion, electric energy is still the most stable and efficient energy form in today's human society, while new energy and distributed power generation are mostly transmitted in the form of DC, and are paralleled with the grid through inverters, voltage stabilizers, and power grids. Therefore, how to maximize the combination of new energy power generation and traditional energy will be an important topic and research direction of human development at this stage. The power transformer is an important part of the power distribution system. It mainly plays the role of voltage conversion, current conversion, impedance conversion, and electrical isolation. With the development of distributed power sources and smart grids, traditio...
