Patent ID: 7706155

Claim:
A circuit for power conversion, comprising: a current mode half-bridge power converter controller, including: an error circuit that is arranged to receive an error sense signal and to provide a first error signal and a second error signal such that the first error and the second error signal are each based, at least in part, on the error sense signal; a stabilization circuit that is arranged to receive a capacitor sense signal; to provide a first stabilization signal such that the first stabilization signal is substantially proportional to a difference between the capacitor sense signal and a first predetermined value at least while the difference is greater than a second predetermined value; and further arranged to provide a second stabilization signal such that the second stabilization signal is substantially proportional to the difference at least while the difference is less than a third predetermined value; and a pulse modulation circuit that is arranged to provide a first switch control signal that is based, at least in part, on the first error signal, the first stabilization signal, and a current sense signal; and further arranged to provide a second switch control signal that is based, at least in part, on the second error signal, the second stabilization signal, and the current sense signal.
