Self-excitation transformation-based voltage stabilizing circuit

Abstract

The invention discloses a self-excitation transformation-based voltage stabilizing circuit which comprises a transformer, capacitors, triodes, resistors and diodes. According to the self-excitation transformation-based voltage stabilizing circuit, unstable direct-current high voltage is transformed into stable direct-current low voltage, unstable direct-current low voltage can also be transformed into stable direct-current high voltage or polarity of the unstable direct-current low voltage can be exchanged, alternating currents are converted into pulsant direct currents through unilateral conductivity of the diodes, and ripple waves in output direct-current voltage is restrained. The self-excitation transformation-based voltage stabilizing circuit is especially suitable for low-power power supply systems, energy sources are saved, output voltage is stabilized by controlling the proportion between pass transistor breakover and blocking time, stabilizing effects are better, efficiency is high, cost is low, and reliability is high.

Description

[0001] technical field [0002] The invention relates to a voltage stabilizing circuit, in particular to a self-excited transformation type voltage circuit. Background technique [0003] At present, for systems with high reliability requirements, there is a serious disadvantage that, regardless of the actual magnitude of the AC voltage component, considerable power is generated across the series transistors, resulting in continuous operation of the transistors at high Under the working temperature state, the aging of the transistor is accelerated, the service life is short, and the stability of the entire system is poor. [0004] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0005] Purpose of the invention: In view of the above-mentioned existing problems and deficiencies, the purpose of the invention is to provide a self-excited conversion type voltage stabilizing circuit with simple structure and strong stability....
