  • DC-TO-DC CONVERTER FOR A HIGH VOLTAGE SYSTEM THAT OPERATES WITHIN A WIDE VOLTAGE RANGE
    Publication number: 20260238110
    Abstract: A method for operating a bi-directional DC-to-DC converter is provided. The DC-to-DC converter can transfer energy from a high voltage network to a low voltage battery as well as from the low voltage battery to the high voltage network. The method includes operating the DC-to-DC converter in a buck mode, switching from the buck mode to a boost mode, precharging a high voltage capacitor such that the voltage across the high voltage capacitor reaches a preset voltage while operating the DC-to-DC converter in a first phase of the boost mode, and charging the high voltage capacitor such that the voltage across the high voltage capacitor reaches a setpoint voltage while operating the DC-to-DC converter in a second phase of the boost mode.

  • METHOD FOR SYNCHRONOUS RECTIFICATION OF A DC-TO-DC CONVERTER
    Publication number: 20260229998
    Abstract: A DC-to-DC converter is provided. The DC-to-DC converter includes an LLC converter circuit which includes a primary side switching component, including switches Q1, Q2, Q3, and Q4, and a synchronous rectifier including synchronous rectifier switches S1, S2, S3, and S4. DC-to-DC converter also includes a controller operatively coupled to the LLC converter circuit. The controller includes control logic to generate a first secondary side driving signal to drive synchronous rectifier switches S1 and S4 using a first current signal of a first shunt resistor connected to the synchronous rectifier switch S4 and to generate a second secondary side driving signal to drive synchronous rectifiers S2 and S3 using a second current signal of a second shunt resistor connected to synchronous rectifier switch S2. A method for synchronous rectification of an LLC converter circuit and a controller for controlling synchronous rectification of a full bridge LLC converter circuit are also provided.
