DC/DC conversion circuit

Of the type that implements the "forward PWM" topology and which comprises a DC/AC converter (M), a self-driven synchronous rectifier (T1,T2), which rectifies the alternating voltage signal coming from the DC/AC converter (M), and a filter (L1,C1) that filters the rectified signal, thereby...

Beschreibung
Zusammenfassung:	Of the type that implements the "forward PWM" topology and which comprises a DC/AC converter (M), a self-driven synchronous rectifier (T1,T2), which rectifies the alternating voltage signal coming from the DC/AC converter (M), and a filter (L1,C1) that filters the rectified signal, thereby obtaining the DC output voltage from the DC/DC conversion circuit. This DC/DC conversion circuit is characterised in that the DC/AC converter (M) 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 (T1,T2) of the self-driven synchronous rectifier.
