DRIVE OF HIGH-VOLTAGE SEMICONDUCTOR DEVICE

摘要

PURPOSE: A driving apparatus for a high-voltage semiconductor device is provided to prevent the dielectric breakdown of a power supply unit by using a transformer and a current transformer. CONSTITUTION: A first side of a transformer receives common electricity. The second side of the transformer is connected to a bus bar. A plurality of current transformers(150) supplies low current to a power supply unit. The current transformer supplies current to an electric power supply circuit part(160). The electric power supply circuit part supplies current to a driving apparatus of a high-voltage semiconductor.
