Abstract The capacitor energy-stored bidirectional transformer belongs to an electronic power transformer, and is characterized by that it adopts the forestage and afterstage series-connection worked transformer structure, in which the forestage transformer is a three-phase full-wave booster transformer formed from power tubes Ta, Tb and Tc and diodes of Da1, Db1,Dc1,Da2,Db2 and Dc2 and capacitor Ca, and is used for transferring D. C. power energy into electric machine, and its afterstage is a step-down transformer formed from power tube Tr, diode Dr, inductor Lr and capacitor Cd, and its action is that when the main switch is switched off, the winding can induct magnetic energy and when it is braked, the mechanical energy of electrid machine can be converted into electric energy, and fed back into power supply. Its circuit structure is simple and its reliability is good.
