<font size=3D"2">I made the power supply which makes about +30V with +5V pow=
er supply.</font><br>
<font size=3D"2">The direct current is changed into the alternating
current by the oscillator which used the schmitt trigger inverter which
has the hysteresis characteristic and the resonance circuit. The high
DC voltage (+50V) is made with the alternating voltage using the
voltage amplification rectification circuit.</font><br>
<font size=3D"2">The output voltage of this circuit changes mainly when
the load changes. So, this power supply can be used only as the power
supply of the circuit that the load is constant or the circuit which
doesn't have a problem even if the voltage changes.</font><br>
