Abstract
The present application relates to an isolated drive circuit, of the type commonly employed as high side drivers, for providing a drive signal to a semiconductor switch. The isolated drive circuit comprises a transformer with primary and secondary windings. The circuit further comprises a primary side circuit having a plurality of switches arranged in a bridge configuration with the primary winding positioned across the output of the bridge and a secondary side circuit connected to the secondary winding of the transformer and having a drive circuit output for providing a drive signal to the semiconductor switch. The advantage of this approach is that the entire circuit can be constructed as a module for use as a single component on a circuit board without requiring additional external components.
