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 post discuses how to modify an ordinary square wave inverter using IC 4047 into a modified sine wave inverter through PWM technology. The idea was requested by Mr. Philip I am a Nigerian living in Nigeria and I have been an avid follower of your blog and.... -
This inverter circuit can be used to power electric razors, stroboscopes and flash tubes, and small fluorescent lamps from a 12 volt car battery. In contrast to the usual feedback oscillator type of inverter, the oscillator of this inverter is separate from.... -
12V car battery is recomended to be used as the input, transistor 2N3055 is used as the amplifier. It will deliver the power output up to 100W and you can use this inverter for battery charger, emergency light and other electronic appliances... -
You can use 12 V car battery as the 12V input power source. Adjust the potensiometer R1 to get the 50Hz output frequency. Use a 10 A fuse in series with the battery as shown in circuit... -
This 12 VDC to 240 VAC Inverter circuit are not using special components such as the torodial transformer found in many inverters circuit.... -
This simple 12VDC to 220VAC inverter circuit 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.... -
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.... -
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.... -
In DA3, DA5, VT1, VT2 assembled the first channel of the VLF class D. The second channel, respectively, collected on DA4, DA7, VT3, VT4. At the output of the first and second channels are formed antiphase sine wave VLF.. -
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.... -
Afshin Izadian at Indiana University has invented a new power inverter that employs just a single switching transistor and generates infinite-level voltages.... -
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.... -
The electric utility grid-connected photovoltaic (PV) system is an important technology for future renewable energy applications.... -
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.... -
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.... -
All the stages involved are actually for enabling a frequency response of 20 to 100kHz, though here we wont need such high degree of frequency response, I didnt eliminate any of the stages as it wouldnt do any harm to the circuit. The first stage consisting.... -
It is recommended to Have a Fuse in the Power Line and to always have a Load connected , while power is being applied. The Fuse should be10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw... -
The inverter circuit has a central component, the CMOS 4047, and converts a 12V DC voltage to 220V AC voltage. 4047 is utilised as a astable multivibrator. At pin 10 and 11 we find a rectangular symmetrically signal which is amplified by tow Darlington.... -
Step up part of this inverter circuit using a transformer 12VCT/500VA in secondary and primary 0 - 220V. While the frequency is determined by the flip-flop which is set to 50 Hz...

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
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.... -
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.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
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,.... -
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.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
