Abstract

The invention discloses a time-base phase-control direct-current stabilized power supply which is mainly composed of a trigger, a phase-control silicon controlled rectifier, a trigger synchronous switch, a delay capacitor, a trigger control circuit, a phase-control synchronous signal source and a trigger circuit power supply. The trigger selects a 555 time-base integrated circuit chip with excellent performances and low price and is specifically connected with the phase-controlled silicon controlled rectifier, the trigger synchronous switch, the delay capacitor, the trigger control circuit andthe phase-control synchronous signal source to form a unique time-base phase-controlled trigger circuit. Compared with the existing phase-control direct-current voltage-stabilizing power supply, thetime-base phase-control direct-current stabilized power supply has a simple structure because of avoidance of a complex discrete component circuit and a single-chip microcomputer control system and has advantages of great anti-interference capability and high working stability and reliability. Because of the simple structure, the core component 555 chip is low in price and the cost of the phase control trigger circuit is greatly reduced.

Description

technical field [0001] The invention belongs to the field of electronic technology phase-controlled DC stabilized voltage power supply, in particular to a time-base phase-controlled DC stabilized voltage power supply. Background technique [0002] There are two types of phase-controlled trigger circuits in existing phase-controlled DC stabilized power supplies, namely discrete and integrated. [0003] The discrete type has poor reliability and stability, complex phase control circuit, difficult adjustment, and high power consumption. [0004] Although the modular integrated type has better performance, it is expensive and mostly depends on imports. [0005] The existing phase-controlled DC stabilized power supply cannot meet the requirements of excellent performance and low price. Contents of the invention [0006] The technical problem to be solved by the present invention is to provide a time-based phase-controlled DC regulated power supply, which solves the problems o...
