Abstract: A series-resonant power converter (10) comprising a transformer (100), a resonant tank circuit (120) having a piezo-electric crystal (122) as the resonant element and a series-connected resonant capacitor (124). First and second switches (132 and 134) are connected to the transformer (100) and are driven by voltages at windings of the transformer so as to alternately turn on. The piezo-electric crystal (122) self-oscillates to store and release energy and thereby charge and discharge the capacitor (124). Moreover, as a result of the self-oscillation of the resonant circuit (120), the switches (132 and 134) are alternately driven in synchronism with the charging and discharging cycle of the capacitor (122) through windings of the transformer (100). No additional switching circuitry is needed to achieve proper oscillation of the resonant tank circuit (120).

Abstract: A method and device are provided for reducing RF transmission interference to a wanted signal of an interactive TV network which is impaired by an interfering signal present on a terrestrial and satellite RF network. The wanted signal is received in the presence of the interfering signal so as to obtain a received wanted signal in the presence of the interferer. The interfering signal transmitted by the satellite network is duplicated and delayed so as to obtain a received interfering signal similar to the interfering signal present with the wanted signal. The received interfering signal is subtracted from the wanted signal in the presence of the interfering signal, so as to deliver a received wanted signal free of interfering signal.
