ABSTRACT:
A power supply comprises a first coupled to receive AC mains power that provides a first power level, a second stage that receives the first power level and that provides a second power level, a third stage that receives the first power level that provides a third power level, and a pulse width modulated switching block comprising a first modulation input, a second modulation input, the first modulation input receives a signal indicative of a voltage, current or power at the second stage output and the second modulation input coupled to receive a signal indicative of a voltage, current or power at the third stage output. The pulse width modulated switching block varying operation of the second stage to vary the second power level according to the signal indicative of the voltage, current or power at the second stage output and the pulse width modulated switching block varying operation of the third stage to vary the third power level according to the signal indicative of a voltage, current or power at the third stage output.
