Abstract

See full text

An IC is coupled to a power stage having a first half bridge having first and second transistors and a second half bridge having third and fourth transistors. A controller has a first control output to provide first-fourth control signals to the first-fourth transistors. The controller asserts the first-fourth control signals to implement a state sequence. The state sequence includes a first state in which the first and fourth transistors are ON, a second state in which the first and third transistors are ON, a third state in which the second and fourth transistors are ON, and a fourth state in which the second and third transistors are ON. During each switching cycle, the controller implements the first and fourth states with one of the second or third states implemented between the first and fourth states, with every n switching cycles alternating implementation of the second or third states.
