  • Publication number: 20240039438
    Abstract: An apparatus and method for determining electrical characteristics has an acquisition circuit and a control circuit. The control circuit causes a first modulation circuit to issue a first set of modulated signals to a first source of alternating current energy, wherein the first set of modulated signals has a first deadtime and wherein a high side switch and a low side switch of the first modulation circuit are turned off. The control circuit further causes the acquisition circuit to acquire a first electrical characteristic of the first source of alternating current energy from the first source of alternating current energy during the first deadtime.

  • Patent number: 10862294
    Abstract: An apparatus includes a pulsed-width modulation signal corresponding to a cutoff voltage, a periodic signal generation circuit, a comparator, and logic. The comparator is configured to compare a voltage input with an output of the periodic signal generation circuit and, based on a comparison of the voltage input with the output of the periodic signal generation circuit, generate another pulsed-width modulation signal. The logic is configured to compare the pulsed-width modulation signal and the other pulsed-width modulation signal to determine whether the voltage input has reached the cutoff voltage.

  • Patent number: 10763747
    Abstract: A power limiter for a switched mode power supply includes an operational amplifier and a comparator circuit. The operational amplifier is configured to receive an input voltage supplied to the SMPS as a first input and a reference voltage as a second input. The comparator circuit is configured to receive an output of the operational amplifier, receive a current sense signal, and generate an output signal configured to control a power generator. The output signal is based on a comparison between the output of the operational amplifier and the current sense signal.
