  • Publication number: 20220255416
    Abstract: A soft-switching power converter includes a main switch, an energy-releasing switch, and an inductive coupled unit. The main switch is a controllable switch. The energy-releasing switch is coupled to the main switch. The inductive coupled unit is coupled to the main switch and the energy-releasing switch. The inductive coupled unit includes a first inductance, a second inductance coupled to the first inductance, and an auxiliary switch unit. The auxiliary switch unit is coupled to the second inductance to form a closed loop. The main switch and the energy-releasing switch are alternately turned on and turned off. The auxiliary switch unit is controlled to start turning on before the main switch is turned on so as to provide at least one current path.

  • Publication number: 20220239230
    Abstract: An isolated conversion apparatus with magnetic bias balance control includes an isolated converter, a controller, and a magnetic bias balance circuit. The isolated converter includes a transformer, and a primary side of the transformer includes a primary-side winding and at least one switch bridge arm. The controller is coupled to the at least one switch bridge arm, and provides a pulse width modulation (PWM) signal group to control the at least one switch bridge arm. The magnetic bias balance circuit is coupled to two ends of the primary-side winding and the controller, and provides a compensation voltage to the controller according to an average voltage of a winding voltage across the two ends of the primary-side winding. The controller adjusts a duty cycle of the PWM signal group according to the compensation voltage to correct the magnetic bias.
