METHOD AND APPARATUS FOR INTEGRATED CABLE DROP COMPENSATION OF A POWER CONVERTER

摘要

An integrated circuit controller includes a switching control circuit coupled to output a drive signal to control switching of a switch to regulate an output power of a power converter to be coupled to a distribution network. An oscillator is coupled to output a clock signal coupled to be received by the switching control circuit. The switching control circuit is coupled to output the drive signal in response to the clock signal. A cable drop compensator is coupled to output a compensated reference voltage signal coupled to be received by the switching control circuit in response to a switching signal from the switching control circuit. The switching signal is representative of the drive signal. The cable drop compensator is coupled to adjust the compensated reference voltage signal proportionately to a load current to compensate for a distribution voltage across the distribution network.
