Abstract

PURPOSE: To lower the current rating of thyristors forming an inverter, by successively changing the combinations of the thyristors, which conduct direct currents every time direct current braking is applied, among the thyristors.
CONSTITUTION: Two thyristors among thyristors 4U∼4Z constituting an inverter circuit 4 are conducted, direct currents are let flow between the two phases of a three-phase inducton motor 5 and direct current braking is applied. Conditions I∼VI are each brought by the conduction of any thyristor at that time, and the combinations of the thyristors are altered every time the direct current braking is applied. Thus, the current rating of the thyristors can be lowered without concentrating conduction to specified thyristors because the combinations of the thyristors shift even if the direct current braking is frequently applied.
