Abstract
A controller for a power converter. The controller is configured to provide a plurality of switching signals to a power converter for use in modulating an output voltage thereof, wherein the controller comprises: one or more comparators, each configured to compare an instantaneous value of an input carrier signal with a reference signal, and output a respective signal; circuitry configured to receive the respective signal(s) from the one or more comparators and transmit a first switching signal for transmission to a first switch and a second switching signal for transmission to a second switch, wherein the second switching signal is a negative of the first switching signal such that they form a first complementary pair; a further comparator configured to compare the reference signal with zero, and output a respective signal.
