System and Method for Generating a High Frequency Switching Signal for a Power Converter

Abstract:

A control device (110) includes a first multiplexing unit (202) configured to segregate a first PWM signal having a first switching frequency into a second PWM signal having a second switching frequency and a third PWM signal having a third switching frequency. Also, the control device (110) includes an integrator unit (204) configured to generate a first integrated signal and a second integrated signal based on the second PWM signal and the third PWM signal, and a modulator unit (206) configured to receive the first integrated signal and the second integrated signal and generate a modulation signal based on the first integrated signal and the second integrated signal. Furthermore, the control device (110) includes a generator unit (208) configured to receive the modulation signal and generate a fourth PWM signal having a fourth switching frequency different from the first switching frequency based on the modulation signal.
