  • Control circuit for synchronous rectifiers in DC/DC converters to reduce body diode conduction losses
    Patent number: 6870747
    Abstract: A controller for a switching power supply having first and second synchronous rectifiers that minimizes the reverse recovery time and body diode conduction losses of each of the synchronous rectifiers. The controller includes a first controller that predicts the optimal turn-on and turn-off time of the first synchronous rectifier as a function of voltage measurements of the previous switching cycle and the timing of the pulse width modulator signal in the current switching cycle. The controller also includes a second controller that predicts the optimal turn-on and turn-off time of the second synchronous rectifier as a function of voltage measurements of the previous switching cycle and the timing of the pulse width modulator signal in the current switching cycle.

  • Control method to reduce body diode conduction and reverse recovery losses
    Patent number: 6396250
    Abstract: A DC-to-DC converter to convert a first DC voltage to a second DC voltage includes a first switch connected to input the first DC voltage, a second switch, the first switch and the second switch being controlled by an input signal to generate the second DC voltage, the first switch and the second switch being connected to a control reference, and a control circuit to control the delay of the input signal by monitoring the control reference around an optimal delay point.
