A blocking oscillator including a transistor amplifier with a feedback transformer having a main winding in the collector circuit and a feedback winding in the base circuit. The feedback winding also serves as an energy-recovery winding by having a diode connected in series with it. The diode is poled such that, when the amplifier is not conducting, the magnetic energy stored in the transformer is fed back to the power supply.
