PURPOSE:To improve an efficiency of a generated electromagnetic energy by inserting an impedance in series with a charging diode connected to a condenser in reverse polarity to an electric charge and further by connecting a diode in parallel and reverse polarity to a switch element. CONSTITUTION:A commercial AC power source 1 forms a half-wave voltage- doubler rectification circuit together with a condenser 2 and diodes 3, 4, and a rectified DC is charged into a condenser 6. This charge is discharged through a coil 7 by a thyristor 9, which is turned on by receiving a firing pulse periodically into a gate from a gate circuit. If a resistor 5 is connected in series with the diodes 4, 3 in order to prevent the aforementioned discharge, an electromagnetic energy of the coil is converted into a voltage energy of reverse polarity and charges the condenser 6. Furthermore, if a diode 8 is connected in parallel with the thyristor 9, the charge of reverse polarity charged in the condenser 6 is discharged through the diode 8 and the coil 7, therefore, a current of just one cycle flows through the coil. A voltage induced in a conductor nearby the coil equals to a differential wave form of that current, exhibits three pulses, i.e. upward, downward and upward pulses, as compared with the ordinary one upward pulse, and has an almost threefold electromagnetic energy. |
