Problems solved by technology

The DC system of the substation or power plant has three major characteristics, (1), the power supply voltage is high, and the power is large (mostly DC 220V)
(2) There are many branch lines, the path is long and wide, and the positive and negative poles cannot be grounded
At present, these requirements cannot be well realized by ordinary DC power supply systems.

Abstract

This invention relates to one digital control stable power circuit structure without impacting, which adopts alternating and direct power exchange module input end connection of electricity, wherein, the output end is connected to direct power exchange module; the direct current power exchange module is connected to the anti-direction punching combination circuit; couple and relay control circuit connects main and prepare source sample circuit to isolate, trace circuit and adjust output voltage; the production spot needs direct current system for running to monitor the system isolation.

Description

technical field [0001] The invention relates to a digitally controlled voltage stabilized power supply circuit structure for switching between main and standby power without impact, specifically a set of high-voltage power supply for 1000W / 220V standby power to follow the main power in time, and to realize switching between main and standby power without impact when necessary Precision regulated power supply circuit, which has the function of main and backup power isolation. Background technique [0002] At present, there are two kinds of known regulated power supplies: 1. One is a regulated power supply with a fixed output voltage; 2. The other is a regulated power supply with a controllable output. The DC system of the substation or power plant has three major characteristics, (1), the power supply voltage is relatively high, and the power is relatively large (mostly DC 220V). (2) There are many branch lines, the path is long and wide, and the positive and negative poles ...
