ing device. Driving circuit generally have a role in isolation, often coupling transformer to achieve the high-voltage power switching devices incentive isolation between the input and output stages and, while both when the power switching device is turned off, reverse bias is applied, to accelerate the device on and off. When the drive MOSFET device, a conventional drive circuit is driven by a transformer to achieve. Taking into account the leakage inductance and lead inductance drive transformer to the main MOSFET having a large Cg-s high-speed charging and discharging cause difficulties, therefore, the usual way is to use a MOSFET driver drive transformer having a smaller Cg-S of the totem type driving circuit then this circuit driven by the main MOSFET. As shown, the drive transformer primary input is the output signal of the drive signal control circuit, the output after shaping circuit shaping process after isolation transformer. Transformer isolators, optocouplers isolate both have anti-interference function, after shaping by Totem drive circuit drives the main MOSFET tube.
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.....
