Hybrid control technique for power converters

Abstract

A power conversion circuit includes a high-side MOSFET and a low-side MOSFET. A conduction terminal of the high-side MOSFET is coupled to a conduction terminal of the low-side MOSFET at a half-bridge (HB) circuit node. The high-side MOSFET is switched off. Voltage potential transitions of the HB circuit node are counted while the high-side MOSFET and low-side MOSFET are off. Assertion of a control signal to the low-side MOSFET is postponed for two voltage potential transitions of the HB circuit node after the high-side MOSFET is switched off. The low-side MOSFET is switched off by de-asserting the control signal to the low-side MOSFET. Switching on the high-side MOSFET is postponed for two voltage potential transitions of the HB circuit node after switching off the low-side MOSFET.
