Abstract

The invention discloses a voltage regulation power supply. The voltage regulation power supply comprises a step up transformer, a main circuit and a control circuit. The voltage regulation power supply is characterize in that the main circuit comprises six thyristors and every two of the thyristors are reversely connected in parallel and then are connected in series between a primary side of the step up transformer and a power supply; the control circuit comprises a signal sampling circuit, a single-chip microcomputer and a thyristor trigger pulse circuit; a secondary side of the step up transformer is connected to a DC high voltage signal collector through a rectifier; the DC high voltage signal collector is transmitted to the single-chip microcomputer through the voltage regulation circuit and an AD converter; the single-chip microcomputer calculates an electricity conducting angle of each thyristor according to signals inputted by the AD converter and the six thyristors are controlled through a thyristor trigger pulse circuit; a synchronous circuit is connected to the single-chip microcomputer to make the phase of the pulse signal outputted by the thyristor trigger pulse circuit be in synchronization with that of voltage on the secondary side of the step up transformer.

Description

technical field [0001] The invention relates to a voltage regulating power supply. Background technique [0002] The high-voltage rectification system of high-frequency induction heating equipment has always used mercury-filled thyratrons in the past, which have very strict requirements on the working environment, and are prone to back arcing, high failure rate, low work efficiency, long warm-up time, high power consumption, and easy Generate a large number of harmonics, seriously polluting the power grid. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a voltage regulating power supply to solve the problems of back arcing, high failure rate, low work efficiency, long warm-up time and high power consumption in the prior art. A technical problem that is prone to generate a large number of harmonics. [0004] In order to solve the above technical problems, the technical solution adopted in...
