    Abstract: A power converter control system is provided which combines a pulse train regulation control technique with a pulse train optimization technique, to control the output level of the power converter, while maintaining optimal performance for other power converter parameters. The power converter control system describe herein provides versatility not previously available in power converter control systems by providing features such as quasi-resonant mode control, discontinuous mode control, and/or power factor correction. A pulse optimizer adjusts or customizes, for example, the ON time, duty cycle or frequency of pulse train pulses output by a pulse generator. The adjusted pulses are gated by a pulse rate controller to selectively actuate a power switch, thereby regulating the output power level and optimize the overall performance of the power converter.
