<p>A circuit for limiting the output voltage (Vc) from a power transistor (T1) connected in series with a resonant load (ZL) between a first pole (Vs) of a supply voltage generator and a second pole of the generator (GND), comprises a semiconductor junction element (40), in particular a diode of the SCR type, having an anode terminal (A) connected to the first pole (Vs) of the supply voltage generator, a cathode terminal (K) connected to a common circuit node (Vc) between the power transistor (T1) and the resonant load (ZL), and a control terminal (G) connected to a reference voltage of predetermined value (E). <IMAGE></p> |
