Vector electric energy converter based on direct-current power supply flexible control

Abstract

A vector electric energy converter based on direct-current power supply flexible control is characterized in that a bipolar direct-current power supply positive electrode end (2), a direct-current power supply positive and negative electrode common end (3) and a direct-current power supply negative electrode end (4) are connected into a direct-current power supply regulator (14) and a bus reactor (15), a DC / AC inverter is not adopted, a new energy direct-current power grid is suitable for being constructed, and in a vector electric energy conversion mode, alternating current and inductive load are adapted to power supply of a direct-current power supply bus system of the micro-grid; a function selection encoder (5) and a display and operation keyboard (6) are used for setting related operation data and modes, an isolation and transmission module (13) is used for transmitting related information, a double-MCU multi-chip assembly (28) is used for carrying out data processing and transmission, a direct-current power supply regulator (14) is instructed to carry out power distribution on the multi-path direct-current voltage-stabilizing source output port (34) according to load characteristics, a plurality of single electrical loads are supported to be connected to a direct current bus of a new energy direct current power grid, and a novel direct current power grid power supply mode is formed.

Description

technical field [0001] The invention relates to the field of "a vector electric energy converter based on flexible control of DC power supply", which solves the problem of the DC bus power supply mode in which the industrial automation drags and the inductive load of household appliances adapts to the DC power network. Background technique [0002] In the frequency converter of the prior art, its input power is an AC power supply, which drives an industrial motor and adjusts its speed in the state of the AC power supply system. Its disadvantages are: it cannot be applied to the microgrid DC power supply power supply system, and the way to drive the load is single, and it is not suitable for the field of household appliances. Contents of the invention [0003] In order to overcome the above defects, the present invention provides "a vector power converter based on flexible control of DC power supply", which is suitable for multiple single loads of high-power resistive, capa...
