    摘要： A converter for raising a weak input DC voltage of 0.3 volts or less to an output voltage has a blocking oscillator and a field-effect transistor included in the oscillator. The transistor having a base earthed is of the enhancement type activated by a gate-source voltage equal to or lower than the input, and the oscillator is activated responding to the gate-source voltage, so that pulses are generated as the output. Typically, the oscillator is composed of a resistor and a condenser connected in series through a lead and between an earth and an input line, a transformer whose secondary winding is connected to transistor's gate and the lead, with a primary winding being connected to the input line and the transistor's drain, and a diode earthed and having a cathode connected to the gate. An electromotive force induced through the secondary winding when the transistor is inactivated has positive and negative poles directed to the condenser and the gate, respectively.
