Three Phase 6 Pulse Inverter
One of the primary things i wanted to do with my Arduino was turn my generators into motors. My simple generators were not simple to turn into motors but this proved to be particularly tricky with my three phase generator. Doing this requires me to create a three phase inverter. The first time I looked at a circuit for this, I thought it would...

Just connect 22k fixed resistors across each transistor base and ground and then you may connect the 50K Dual pot leads across these resistors, that should imitate a 10k pot variations quite closely. Hi Swagatam, so just to be clear, you want me to remove the 10K resistors connected to the Base of each Transistor and replace with 22K resistors...

The MOSFET`s could be in parallel pairs for even more power. Just give each its own 470 © gate resistor and a 22k © from each gate to source. The large 1000 µF capacitor and 47 © resistor used to clean up the voltage spikes coming from the transformer centre tap into the positive rail and protect the PIC from them.
500w power inverter circuit diagram based tip35c
There is certainly only one variable resistance in this circuit diagram which is made use of to adjust frequency of 240V AC output current. It is best to have a frequency meter to adjust this frequency of 50HZ to 60HZ as per your requirement. Please don`t power up any device using your inverter just before frequency adjustment for the reason...

full bridge inverter with mosfet ir2110
For the full bridge inverter circuit i planned to use IRF2807 (75V Vds, 82A Ids) and Two IR2110 for the driver. I never use IR2110 before and failed many time when i want to make a H-Bridge for DC motor last year. My DC input voltage is 34V (2 series solar panel), The power rating is about 100Watt so the MOSFET should able to drain about 10A max c

Afshin Izadian at Indiana University has invented a new power inverter that employs just a single switching transistor and generates infinite-level voltages..
bidirectional power inverter
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 can generate a negative output from a positive supply or a positive output from a negative supply. When the circuitstarts up,...

flyback inverter for fluorescent lamp 15
A fluorescent lamp has quite a few unique requirements to get it to start up and stay illuminated. How does this flyback converter manage to do these things I had first looked around to see if I could find a schematic for this fluorescent lamp assembly, but nothing turned up for me. However, the parts count was low enough, and circuit board...
A 100 Watt inverter circuit using minimum number of components. I think it is quite difficult to make a decent one like this with further less components. Here we use CD 4047 IC from Texas Instruments for generating the 100 Hz pulses and four 2N3055 transistors for driving the load. The IC1 Cd4047 wired as an astable multivibrator produces

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to find something potentially valuable, hidden a few centimeters below the soil. So many...

Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...
