1. A method of controlling an amount of power delivered by a power converter to a solid state lighting load, the method comprising:

  • determining whether a dimmer is present between a voltage source and the power converter based on a rectified input voltage from the voltage source; and

    when the dimmer is determined to be present, adjusting an operating point of the power converter to increase the amount of power delivered by the power converter to the solid state lighting load by a compensation amount, so that the increased amount of power is equal to an amount of power delivered by the power converter when the dimmer is not present.
