6v voltage inverter

The PGPI is a 6V to 12V converter for vehicles that still have a 6V, positive ground electrical system. It is necessary if you are still running positive ground for all of our radios, which run on a 12V, negative ground electrical system. The PGPI positive ground inverter comes with detailed wiring instructions.

All the designs employ a single PNP transistor and transformer, connected in the feedback mode for generating the oscillations. The mini inverter circuit demonstrated in the following figure can produce a highest AC output of 220 volts if it is powered through any battery between 1.5 V and 6 V battery.

This 3 V to 220 V inverter circuit may draws around 70 ma from the 3 V battery (B1). The inverter circuit seen above is built around a straightforward astable multivibrator, which pushes and pulls its output via the secondary of a center-tapped, 12-volt step down power transformer. The circuit is powered by 6 volts of DC from four AAA batteries.

The maximum drain from the battery at 1.5 V supply will be roughly around 100 ma. R1 will alter the DC output between 60 and 80 volts, in the absence of a load. The next 3 V to 220 V inverter circuit is designed to work in a blocking oscillator mode having an operating frequency set at around 400 Hz.

The next 3 V to 220 V inverter circuit is designed to work in a blocking oscillator mode having an operating frequency set at around 400 Hz. The transistor used can be any PNP power transistor. The center tap transformer can be any standard step down transformer. This transformer provides the feedback and the voltage boosting both together.
