Double-sided grinding high-precision regulated power supply

Abstract

The invention provides a double-sided grinding high-precision stabilized voltage supply, which comprises a primary solenoid connected with a live wire, a first secondary solenoid connected with a null wire for compensating voltage and a second secondary solenoid with motor carbon brushes on double surfaces, wherein the secondary solenoid is electrically connected with a power supply main control panel; the power supply main control panel is connected with a motor control terminal, a carbon brush abrasion detection module and a current transformer through a circuit; the power supply main control panel finishes forward and reverse operation control of the motor carbon brushes on the front surface and the back surface by controlling the motor control terminal to finish boost and buck control on the second secondary solenoid, so that the overall output voltage reaches a stable state; stable output voltage can be provided; the double-sided grinding high-precision stabilized voltage supply can normally work under the condition of a relatively large load; furthermore, motor-driven circuit and program board of the stabilized voltage supply can finish driving of double-sided grinding; and the double-sided grinding high-precision stabilized voltage supply can be commonly used at different rated power and is the stabilized voltage supply with motor voltage regulation.

Description

Technical field [0001] The invention belongs to the technical field of voltage stabilizing power supplies, in particular to a high-power fully automatic AC stabilizing power supply that can be used universally under the condition of different grid frequencies. Background technique [0002] A stabilized power supply is an electronic device that can provide a stable AC or DC power supply for the load, usually consisting of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. At present, most of the high-power voltage regulators on the market are composed of two parts, one main and one pair of wire packages, and the main control board based on the embedded single-chip microcomput...

AI Technical Summary

Problems solved by technology

However, the voltage regulation range of the voltage stabilizer attached to the motor on one side is small, and the load capacity of one main and one pair of two wire packages cannot keep up with the market demand.
