12 Volt DC to 120 Volt AC Inverter
This Inverter takes 12 volt DC and steps it up to 120 volt a. c. The wattage depends on which transistors you use for Q1 and Q2, as well as the "Amp Rating" of the transformer you use for T1. This inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts __ Designed by Aaron Cake
12 volt Inverter-Very Basic type
This circuit will provide a fairly stable "Square Wave" Output Voltage. Frequency of operation is Mainly determined by the 220 uF Feedback Caps. Currently about 60 Hz. Various "off the shelf" transformers can be used. __ Designed by G.L. Chemelec
12-240V Inverter
This vibrator inverter provides 240VAC at 60W from a 12V battery __ Contact: blehack @ yahoo dot com
12kv Power Supply
If you need about 12, 000 volts DC for an ion generator this circuit might be the ticket. It draws power from the 120vac power line but it uses a small 6KV camera flash trigger coil. The output signal is isolated from the power line. . . Circuit by David Johnson P.E.-March, 1999
12V Fluorescent Inverter
This is a low-cost project for 20 or 40 watt fluorescent tubes. However the most efficient is to use a 40 watt tube (or two 20 watt tubes in series). It's a circuit you can put together from junk box components or build from a kit. It's very simple to build and requires no printed circuit board __ Contact: Collin Mitchell

2 Amp Power Supply
This handy power supply has an output of 0v to 12v at 700mA with a transformer that is rated at 1-amp (such as M-2155) or 1.4amp for a transformer that is rated at 2-amp (such as M-2156). Your local electronics shop or model railway supply will have these __ Contact: Collin Mitchell
300ma DC-to-AC Converter
This circuit was used to provide battery backup to a device that had an AC (output) wall transformer. Due toquasi-sine-wave output and imprecise 60Hz output frequency, some devices might not work properly. Peak output isDC input voltage minus about 20 __ Designed by Andrew R. Morris
40A Power Supply Unit
Capable of running at full power at 100% duty cycle.
500W Low cost 12V to 220V inverter
Using this circuit you can convert the 12V dc in to the 220V Ac. In this circuit 4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer. __ Designed by Ashad Mustufa
555 DC-AC Inverter
This DC-to-AC inverter schematic produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4. The 555 feeds its output (amplified by Q1 and Q2) to the input of transformer T1, a reverse-connected filament __ Designed by Tony van Roon VA3AVR
6 to 12 Volt Converter
This circuit can provide up to 800mA of12V power from a 6 Volt supply. The circuit is simple, about 75% efficient and quite useful __ Designed by Aaron Cake

AC to DC Power Supply, Non-Isolated Off-Line
This compact efficient circuit can provide up to 100ma of a regulated 5 volts from an AC power source ranging from 20vac to 120vac . . . Hobby Circuit designed by David Johnson P.E.-July, 2006
Bidirectional Power Inverter
08/02/01 EDN-Design Ideas If you want to swap charge in either direction between unevenly loaded positive and negative battery buses, you need an inverting dc transformer. One implementation is the symmetrical flyback converter shown in Figure 1. The circuit Design by Tom Napier, North Wales, PA |
