Inverter as High Voltage low Current Source Circuit Diagram
The Inverter as High Voltage low Current Source Circuit Diagram is capable of providing power for portable Geiger counters, dosimeter chargers, high resistance meters, etc. The 555 timer IC is used in its multivibrator mode, the frequency adjusted to optimize the transformer characteristics.
When the output of the IC is high, current flows through the limiting resistor, the primary coil to charge C3. When the output is low, the current is reversed. With a suitable choice of frequency and C3, a good symmetric output is sustained.

Dual Polarity Unregulated PSU For High End Audio Amps
A power supply suitable for use with the hi-fi amplifiers presented in the predeeding project is perfectly simple, and no great skill is required to build (or design) one. There are a few things one should be careful with, such as the routing of high current leads, but these are easily accomplished. Design of this power supply is very simple. A 4 ampere fuse is used to protect the transformer and two LEDs at the end of this circuit are used to indicate power state On and Off. At the output there are 6 capacitors used you can reduce the quantity of these filter capacitors to 2 or according to your own choice.
