Abstract

PURPOSE:To enable the operation of activated power supply of high voltage, by connecting the collector, base and emitter of the transistor (Tr) to the power supply via respectively a resistor, and taking greater the power supply voltage than the avalanche voltage between the base and collector. CONSTITUTION:One side of the activated power supply is connected to the collector of TrQ1 via the resistor R1, and the base of TrQ1 is connected to another side of the power supply via the resistor R3 and the emitter is via the parallel circuit consisting of the resistor R2 and the capacitor C1. The power supply voltage E is set greater than the avalanche voltage VT between the base and the collector of TrQ1. The avalanche breakdown current flows from the collector to base of TrQ1, the potential of the base is higher than that of emitter, and the emitter current flows. Thus, the avalanche breakdown is accelerated and the emitter current increases more. When the C1 is charged with the emitter current, the emitter current is less and the breakdown current is decreased and finally the emitter current stops. When C1 discharges through R2, the emitter current flows again and this is repeated for oscillation. The power supply is of high voltage, allowing to increase the output voltage.
