Direct-current power regulator

Abstract

The invention discloses a direct-current power regulator which comprises an input and output signal interface conversion circuit, a power conversion circuit and a polarity switching circuit. The invention has the beneficial effects that the direct current power supply output realizes continuous voltage and power output under the control of the analog control signal, the voltage range is from 0 to Vmax, the power range is from 0 to Pmax, the electric energy control is more accurate, the use efficiency is more efficient, the waste is less, and the safety is high; according to complex use requirements, output polarities (positive and negative poles) of the direct-current power supply are rapidly switched when being controlled, the direct-current power supply can be universally applied to resistive loads, inductive loads and capacitive loads requiring voltage and power to change, and can bear large impact in voltage and current ranges allowed by a regulator in direct-current power control, integrated design, low-voltage and low-power-consumption direct-current power supply control, high-voltage and low-power-consumption direct-current power supply control and high-voltage and low-power-consumption direct-current power supply control. And the same load can accept different power loads, so that the overall cost is also saved while the volume is saved.

Description

technical field [0001] The invention relates to a regulator, in particular to a DC power regulator, and belongs to the technical field of electric energy control equipment. Background technique [0002] For switching power supplies, the voltage standards of DC power supply products on the market are 24 volts, 15 volts, 12 volts and 5 volts, AC input and DC output, and the place of use is the use of fixed voltage. The current changes with the load, and different loads get different results. Power; the output polarity cannot be changed, and the range and amplitude of current adjustable changes are small; [0003] For power regulators, the products on the market are AC input and AC output, and the power regulator controls the load in the phase-shift control mode and zero-crossing control mode; the phase-shift control mode is realized by controlling and adjusting the conduction angle of the internal thyristor. Changes in voltage and power; the zero-crossing control method is to...

Problems solved by technology

[0005] 1. High power and AC output will cause large inertia, large overshoot, poor stability, increased control difficulty, more factors to be considered, and complicated control circuits during precision control

Due to the large size of the AC power conditioner and the configuration of the external control part, a special electric control box and a large space are required for assembly;

[0006] 2. When using alternating current, the power factor of electric energy is relatively low, and the efficiency is low;

[0007] 3. In the constant voltage place using switching power supply, the voltage cannot be adjusted, and the DC voltage and power cannot be adjusted on the same load
