  • Driving control device and method for power converting system
    Patent number: 8080986
    Abstract: A driving control device and method for power converting system includes power converting circuit and driving control device. The driving control device has an analog/digital convertor, a measuring device, and a control module. The driving control method is the analog/digital convertor receives a inductor current and the parameters of the inductor current from the measuring device, measures the slope parameter of the inductor current according the parameters from Equation 1 and Equation 2, then calculates a duty cycle parameter from the slope parameter of the inductor current and use the duty cycle parameter to generate pulse control signal to perform driving control.
