Abstract
A self-oscillating boost converter includes a resistor-starting network configured to start a charging of the boost converter. A resonant feedback circuit is designed to generate an oscillating signal following the starting of the circuit by the resistor-starting network. A complementary switching network has a pair of complementary common-source connected switches configured to receive the oscillation signal generated by the resonant feedback circuit. The oscillation signal determines a switching rate, or duty cycle, of the complementary pair of switches. A boost inductor is in operational connection with the complementary pair of switches. The switching rate of the complementary switching network acts to determine the boost voltage supplied to a load.
