Bidirectional Regulation Principle of Gong's Half-bridge and Full-bridge Circuits

The inversion circuitry and regulation principles of half-wave and full-wave bridge applied to DC chopping conversion field are the most comprehensive basic circuits and regulation principles applied to DC/AC conversion.In the same way, the corresponding Gong half-wave and full-wave bridge conversion circuits and regulation principles exist too in AC conversion field.What the bidirectional regulation principle of Gong half-wave bridge is that the AC output voltage of an AC chopping voltage regulation circuit is compared with the AC voltage across the center tap of a phase inversion autotransformer''s winding to realize forward-reverse bidirectional regulation for AC voltage. What the bidirectional regulation principle of Gong full-wave bridge is that the two AC output voltages of two AC chopping voltage regulation circuits are compared to realize forward-reverse bidirectional regulation for output voltage.These new principles are extracted from the inventions of multitudinous AC bidirectional chopping voltage regulation circuits and are foundations of realizing bidirectional voltage regulation which contain various new regulation circuits of AC/AC bidirectional chopping conversion. Therefore, 4--12bidirectional electronic switches of phase inversion can be saved in AC chopping voltage regulation, so that the bidirectional voltage regulation circuits can be simplified and their cost Can be lowered.
