Double-ended working core square wave inverter transformer area product formulaBm is the maximum magnetic flux. Transformer primary side of the switch S1 and S2 in parallel with IRF32055 only reason why parallel, mainly because access to the load in the inverter, the transformer primary current is relatively large, parallel to shunt, which can effectively

reduce the switch power, and will not cause damage. PWM control circuit chip SG3524, is a voltage type switching power supply integrated controller, with output current limit, switching frequency is adjustable, error amplifier, PWM comparator and turn-off circuit, which produces a square wave PWM peripheral circuits required very simple. When the pin 11 and pin 14 parallel, the output pulse from 0 to 95% duty cycle, pulse frequency of the oscillator frequency is equal to 1 / 2. When the pin 10 (off stump) plus high, can achieve the blockade of the output pulse, and the external circuit properly connected, you can achieve under-voltage, over-current protection. Using SG3524 regulating the internal op amp that comes with the drive waveform of the output duty cycle D, the 50%, and then reverse after CD4011, got on the tube of the drive waveform of D <50%, this can ensure that the two groups switch drive, have a common dead time. Shown in Figure 3, DC / AC conversion using single-phase output, the form of full-bridge inverter, power inverter for the reduced volume, lower cost, using the frequency out put LC filter. Posed by the four IRF740 bridge inverter circuit, IRF740 maximum voltage 400V, current of 10A, power 125W, using half-bridge driver IR2110 provides driving signal, the input waveform provided by the SG3524, the same way adjustable driver output waveforms of the SG3524 of D <50%, driven by square wave inverter to...
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.....
