More Information
Summary:The utility model relates to an alternate-current stabilized power supply in power electronics. The utility model is mainly composed of an interference suppressor, an input filter, an output filter, a sine energy distributor, an input sampling comparator, an output sampling comparator, a controller, a synchronous circuit and a direct-current power supply. All components are connected and arranged in a shell. The utility model is characterized in that the middle end or the front end of the input filter which is connected with the sine energy distributor is connected with a step-up autotransformer. Simultaneously, the utility model changes the shape of an E-shaped silicon steel sheet in an inductor of the sine energy distributor. The middle convex end is below both ends. An air gap is formed. The utility model adopts the iron shell. The utility model widens stabilized-voltage range, decreases magnetic leakage, and ensures stabilized-voltage quality after being improved.
