Abstract
PURPOSE: To enable corresponding with a polarity reversing and also regenerative braking by connecting thyristors to each diodes of a diode bridge in reverse parallel.
CONSTITUTION: In case when a collector P1 being positive at a powering time a driving current flows through a collector P1, a filter reactor 3, a diode 4a, a motor 11, a smoothing reactor 12, a chopper 10, a diode 7a and a collector P2, and in case when a collector P2 becoming to positive diodes 4a, 7a are changed to diodes 6a, 5a. In case when a collector P1 being positive at a regenerating time a regenerating current flows through a flywheel diode 13, a thyristor 4b, a collector P1, a regenerative load, a collector P2, a thyristor 7b, a smoothing reactor 12 and a motor 11, and in case when a collector P2 becoming to positive thyristors 4b, 7b are changed to thyristors 6b, 5b.
