  • Publication number: 20190341790
    Abstract: In one embodiment, a vehicle pre-charge limiting system is disclosed. The system includes an inverter, a comparator, a latch circuit, and a microprocessor. The inverter inverts a first power signal into a second power signal. The comparator receives a first measured current of the second power signal and compares the first measured current to a predetermined current value. The comparator transmits a first control signal indicative of the first measured current exceeding the predetermined current value. The latch circuit transmits a second control signal to the inverter to discontinue inverting the first power signal and transmits a first latch signal. The microprocessor receives a first sense signal indicative of current of the first power signal and transmits a third control signal to the latch circuit. The microprocessor inverts the first power signal into the second power signal for a predetermined number of output periods.

  • Publication number: 20160087317
    Abstract: Vehicle high-voltage side heater systems and methods are described. In an example, a controller to input a modulated control signal from a low-voltage side is connected to a high-voltage side heater, which is controlled by the modulated control signal from the controller. The controller can be on low-voltage side and not directly connected to a low-voltage side power but does derive the control signal from an input signal, which can be pulse width modulated.
