Abstract
A method of controlling a multiphase power converter including a plurality of sub-converters coupled to provide power to a load is disclosed. Each sub-converter includes a power switch. The method includes selectively and consistently turning on the power switch of one or more of the sub-converters at substantially a same time as a reference signal representing a desired output of the power converter increases. The method further includes selectively and consistently turning off the power switch of one or more of the sub-converters at substantially a same time as the reference signal representing the desired output of the power converter decreases. Other methods, multiphase power converters and controllers for multiphase power converters are also disclosed.
