Abstract:
The invention relates to a half-bridge power converter controller that employs current mode control. The power converter controller includes pulse modulation circuitry, error circuitry, and stabilization circuitry. The stabilization circuitry stabilizes the voltage at the mid-point of a half-bridge power converter input capacitor circuit. The input capacitor circuit mid-point voltage is stabilized by selectively adjusting the on-times of the high-side switch and low-side switch of a half-bridge power converter. This adjustment tailors the current that is provided to the input capacitor circuit and thus maintains the mid-point voltage near a desired value.
