Abstract :
An integrated controller which is optimised for zero-voltage resonant switching of a square-wave bridge power topology is introduced. By modulating the power with phase control high efficiency can be achieved at high frequencies with the added benefit of constant frequency operation. Adaptable to both voltage and current mode control, this IC provides both regulating intelligence and fault protection
