Abstract

The invention relates to an alternating current sine wave electric booster, which comprises, a chopper power switch K1, a after-flow power switch K2, a voltage synchronous signal sampling circuit T, a high-frequency wave generation drive circuit PWM, a filter circuit L and a filter circuit C. Wherein, the input of said chopper power switch K1 is connected to the power resource, while its output is connected to one end of after-flow power switch K2 and the input of filter circuit L; one end of filter circuit C is connected to the output of filter circuit L, while another end is connected to the another end of after-flow power switch K2; the input of voltage synchronous signal sampling circuit T is connected to the power resource, while its output is connected to one input of high-frequency wave generation drive circuit PWM; another end of high-frequency wave generation drive circuit PWM is connected to the potentiometer, while its output is connected to the control ends of chopper power switch K1 and after-flow power switch K2.

Description

technical field [0001] The invention relates to a voltage regulator, in particular to an AC sine wave electronic voltage regulator. Background technique [0002] At present, the AC sine wave electronic voltage regulator is still blank in the market. Traditional voltage regulators include auto-coupling voltage regulators, inductive series voltage regulators, and sine wave power supplies composed of frequency converters, transformers, and LC filter circuits. The first two types are bulky, inconvenient to adjust, and difficult to increase the power, while the latter type has high manufacturing cost, large volume, and difficult filtering. Contents of the invention [0003] The purpose of the present invention is to provide a low-cost, small-volume AC sine wave electronic voltage regulator. [0004] An AC sine wave electronic voltage regulator of the present invention comprises a chopping power switch K1, a freewheeling power switch K2, a voltage synchronization signal samplin...
