1. The primary winding of the synchronic rectifier with a transformer is connected to a high-frequency power generator. The secondary winding is connected to a diode rectifier with a filter and a load. It is equipped with a controlling winding, magnetically coupled with the transformer winding. The output of the controlling winding is connected to a controlling module, consisting of a capacitor and two bidirectional keys. The latter consist of transistors and two diodes. The drain of the first transistor connected to the cathode of the first diode and one conducting plate of the capacitor constitutes the first output terminal of the module. The second output terminal of the module is connected to the second conducting plate of the capacitor and the cathode of the second diode and the drain of the second transistor. The anodes of the first and the second diode and the drains of the first and the second transistor are connected to each other and to the first and the second output terminal of the module. The gate of the first transistor is connected to the third input terminal, while the gate of the second transistor is connected to the fourth input terminal of the module. The third and fourth input terminals and the first and the second input terminals are connected to the input of the controlling generator, according to the Polish patent claim No. 174 595. Unique characteristics: The controlling module (MSSi, MSRi) is connected between the power generator (GM) and the primary winding of the transformer (Tr). |
