1. A controller for controlling a power supply for conversion of power between a source and a load, the power supply including a power switch that, when coupled to the source and cycled ON and OFF, supplies a pulse of power to the load, the controller comprising:

  • pulse generation circuitry for generating switch activation pulses to cycle the power switch, each switch activation pulse produced by the pulse generator defining a new switching cycle; and

    pulse optimization circuitry coupled to the pulse generation circuitry for controlling when a switch activation pulse is generated to initiate a switching cycle.
