Description

technical field [0001] The invention relates to a power supply circuit, in particular to a voltage-stabilized power supply. Background technique [0002] 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. [0003] Therefore need a kind of new technical scheme to solve the above problem. Contents of the invention [0004] Purpose of the invention: In view of the problems and deficiencies in the prior art above, the purpose of the invention is to provide a stabilized power supply with stable performance. [0005] Technical scheme: the technical scheme adopted by the present invention is a ...
