  • DC/DC conversion circuit
    Patent number: 5535112
    Abstract: A DC/DC conversion circuit of the type that implements the "forward PWM" topology includes a DC/AC converter, a self-driven synchronous rectifier which rectifies the alternating voltage signal coming from the DC/AC converter, and a filter that filters the rectified signal, thereby obtaining the DC output voltage from the DC/DC conversion circuit. This DC/DC conversion circuit is characterized in that the DC/AC converter includes means to generate an alternating signal with a square waveform that does not take zero instantaneous values such that no current flows through the body diode of either of the transistors of the self-driven synchronous rectifier.
