便であり、かつ装置全体も重いという欠点があった。Conventionally, as this type of device, a DC-DC converter using a so-called saturated magnetic core type bush-pull oscillation circuit is known. Since the transformer having a saturated magnetic core is very heavy, it is inconvenient to handle during the assembly process, and the entire device is also heavy.

容量素子９は整流回路８の出力電圧に含まれる交流分を
除去するためのものである。The capacitive element 9 is for removing the alternating current component contained in the output voltage of the rectifier circuit 8.

なり、直流電源１２の電圧より高い電圧となる。In the DC-DC converter configured as above,
The DC voltage at the output end of the rectifier circuit 8 is the DC voltage obtained by rectifying the output voltage of the CR phase type oscillation circuit 6, and the rectifier circuit 8.
The voltage is the sum of the voltages of the DC power supply 12 applied to the output terminal C of the DC power supply 12, and is higher than the voltage of the DC power supply 12.

コンバータの出力は安定する。In addition, in the CR phase full oscillation circuit, the oscillation frequency is determined by the values of the capacitive element and resistance of the feedback circuit, so the change in oscillation frequency due to load fluctuation is less than in the conventional saturation magnetic core type bush-pull oscillation circuit. DC-DC
The output of the converter becomes stable.
