DRIVING CIRCUIT OF A POWER ELEMENT FOR IMPROVING A VOLTAGE INEQUALITY PROBLEM

摘要

PURPOSE: A driving circuit of a power element is provided to synchronize two elements for turning off each gate of two elements at the same time by applying a parallel transformer to the driving circuit.;CONSTITUTION: A driver(110) comprises a first driver(DRV1) and a second driver(DRV2). The first driver drives a first power switching element(Q1). The second driver drives a second power switching element(Q2). A transformer(120) for balance has a first winding coil and a second winding coil. The first winding coil connects the first driver to the gate of the first power switching element. The second winding coil connects the second driver to the gate of the second power switching element.;COPYRIGHT KIPO 2013
