Abstract
The present disclosure provides a naturally freewheeling alternating (AC) current chopping main circuit structure. The naturally freewheeling AC chopping main circuit structure includes an AC chopping main circuit (1) and inductive load (2). The AC chopping main circuit includes a chopping switch element assembly (3), two inductance coils (L1 and L2), two diodes (D1 and D2), and a capacitor (C). The two inductance coils and the two diodes are connected to form a closed circulatory circuit while the circulatory circuit implements natural freewheeling of a chopping current in the two induction coils when the chopping switch element assembly is switched off.
