Method and apparatus for integrated voltage drop compensation relating to cable being connected to a d.c. converter

摘要

An integrated circuit controller (119) for a power converter (100) to be coupled to a distribution network (102) includes a switching block (201) that outputs a drive signal (211) to control switching of a switch (208) to regulate an output of the power converter (100). The integrated circuit controller (119) also includes a cable drop compensator (202) that outputs a compensated reference voltage signal (216) to the switching block (201) in response to a switching signal (212). The switching signal (212) is responsive to the drive signal (211). The compensated reference voltage signal (216) is representative of a voltage value that is responsive to a distribution voltage (132) across the distribution network (102) and a load voltage (130) across a load to be coupled to the distribution network (102). The switching of the switch (208) is responsive to the compensated reference voltage signal (216) and a feedback signal (124) .
