Abstract: Operating a gate driver. At least one example is a method of operating the gate driver, the method comprising: de-asserting a drive-low terminal of the gate driver; starting a single timer within the gate driver; and after expiration of the single timer asserting a drive-high terminal of the gate driver responsive to assertion of an in-high terminal of the gate driver; and then de-asserting the drive-high terminal; starting the single timer; and after a second expiration of the single timer asserting the drive-low terminal responsive to assertion of an in-low terminal of the gate driver.

Abstract: A multi-phase power converter includes a digital ramp pulse modulation controller, a digital constant on-time controller, and a driver stage. The digital ramp pulse modulation controller provides a trigger ramp signal in response to an error signal when the multi-phase power converter is not in a green mode, wherein at least a portion of the digital ramp pulse modulation controller is inactive in the green mode. The digital constant on-time controller provides on-time thresholds and off-time thresholds when the multi-phase power converter is in the green mode. The driver stage provides a plurality of drive signals to a corresponding plurality of power stages in response to the trigger ramp signal when the multi-phase power converter is not in the green mode and to the on-time thresholds and the off-time thresholds when the multi-phase power converter is in the green mode.

Abstract: A method of detecting zero crossings in an AC input voltage at an input of a power converter includes measuring, at a first time, a first voltage. If the first voltage is positive: determining that the first time corresponds to a positive half-cycle of the AC input voltage. If the first voltage is equal to zero: a) determining that the first time corresponds to a negative half-cycle of the AC input voltage; b) turning on a high-side switch of the power converter for a first time period; and c) measuring, during the first time period, a second voltage. If the second voltage is less than a first threshold, turning off the high-side switch and repeating b) and c) after a time delay. If the second voltage is less than a second threshold, maintaining the high-side switch in an ON state for a second time period.

Abstract: A power conversion device includes: a first control unit and a second control unit that output a first control signal and a second control signal, respectively; a gate circuit that causes a control signal selected from the first control signal and the second control signal to pass through the gate circuit; and a drive circuit that drives a main circuit based on the control signal that passes through the gate circuit. When the second control signal is selected in the state where the first control signal passes through the gate circuit, the gate circuit interrupts the first control signal and causes the second control signal to pass through the gate circuit as an absolute value of an instantaneous value of an AC current decreases below a threshold current.

Abstract: A control method is disclosed for an asymmetric half-bridge power supply having a resonant circuit, a first switch, a second switch, and an assisting switch. The resonant circuit includes a transformer and a resonance capacitor. The transformer has a primary winding connected to the resonance capacitor and an auxiliary winding connected to the assisting switch. Within a switching cycle, the first switch is turned on for a first ON time to increase an exciting current of the transformer. After the first ON time, the second switch is turned on for a second ON time to decrease the exciting current. Whether a discharge duration of the transformer ends is detected. The assisting switch is turned ON after the end of the discharge duration, making the exciting current negative, so as to assist the first switch achieving ZVS.
