  • Patent number: 11372435
    Abstract: A voltage regulator circuit includes a first voltage regulator having a first output voltage selection pin set and producing a first output voltage based on a first digital signal received at the first output voltage selection pin set, and a second voltage regulator having a second output voltage selection pin set and producing a second output voltage based on a second digital signal received at the second output voltage selection pin set. The first and second voltage regulators are operable in a voltage tracking mode with the output voltage of the second voltage regulator tracking the output voltage of the first voltage regulator when digital signals received at the selection pin sets have a same value. An overvoltage sensor detects overvoltage events at the first voltage regulator. Control circuitry selectively avoids operation in voltage tracking mode as a result of an overvoltage event detected at the first voltage regulator.

  • Patent number: 11368088
    Abstract: Provided is multi-phase interleaving control in a power supply device, the control allowing the pulse widths ?T of respective phases to overlap one another, so as to be adaptable to wideband pulse power control. In applying dead beat control to the multi-phase interleaving, constant current control is performed using combined current of the respective phase current values, and the pulse widths ?T(k) is computed under this constant current control, thereby preventing variation of the pulse widths ?T(k) between the phases, and achieving stable power control. Accordingly, the pulse power control becomes adaptable to wideband. Furthermore, wideband control is possible also in two-level pulse power control that performs control by switching at high frequency between High-level power and Low-level power.

  • Patent number: 11367579
    Abstract: In a method for controlling a relay with a relay contact, switching as an opening operation or a closing operation at the relay is temporally captured with respect to accurate opening or closing of the relay contact in comparison with a switching voltage zero crossing of a switching voltage to be switched. An actual switching time is determined and is corrected by means of further capturing of switching operations. A microcontroller is used for this purpose, and the signals can be digitally captured, that is to say at an A/D input.
