Description

ABSTRACT:
A multiple inverter has an input shut-off circuit receiving a DC energy input and providing two DC outputs; two unit inverters coupled to the input shut-off circuit, each including switching elements, for respectively converting the DC outputs into two AC outputs; and a control circuit coupled to the unit inverters for detecting an accidental overcurrent due to a shoot-through of the switching elements, and turning off the unit inverters. The input shut-off circuit includes circuit elements for interrupting a current path of the DC energy input when the control circuit detects the accidental or faulty overcurrent.
