Control circuits and methods for transitioning between power converter control modes
First Claim
1. A control circuit for controlling a power converter to operate in a first mode and a second mode different than the first mode, the control circuit comprising a first integrator circuit corresponding to the first mode and having an output and a second integrator circuit corresponding to the second mode and having an output, the control circuit configured to transition control of the power converter between the first mode and the second mode such that one of the first mode and the second mode is a controlling mode for a period of time and the other one of the first mode and the second mode is a non-controlling mode for the period of time, and set the output of the first integrator circuit or the second integrator circuit corresponding to the non-controlling mode to equal the output of the first integrator circuit or the second integrator circuit corresponding to the controlling mode.

Abstract
A control circuit includes a first integrator circuit corresponding to a first mode and a second integrator circuit corresponding to a second mode. The control circuit is configured to transition control of the power converter between the first mode and the second mode such that one of the first mode and the second mode is a controlling mode for a period of time and the other one of the first mode and the second mode is a non-controlling mode for the period of time, and set an output of the first integrator circuit or the second integrator circuit corresponding to the non-controlling mode to equal an output of the first integrator circuit or the second integrator circuit corresponding to the controlling mode. Other example control circuits, power converters including a control circuit, and methods for controlling a power converter are also disclosed.
