At present, that utilize in the high-power, high frequency, narrow pulsing application is basically vacuum tubes, for instance: Secondary electron transmitting tube, discharge gap switch, trigatron, hydrogen brake pipe, etc. The main research direction is how to improve the switch speed of the vaccum device of electricity, reduce it to touch off an

d rock, develop it with its high-pressure driving circuit of suitable high speed. But devices such as the vacuum tube, etc loss big, the driving circuit is huge and cooling shortcoming of trouble, etc. ; Meanwhile, in order to protect it fast when the klystron strikes sparks, need to set up complicated crow bar tube and flip flop in the modulator frequently, efficiency and reliability [1 ] of the direct influence modulator of these questions. In recent years, because voltage and power level of the semiconductor device are promoting constantly, correlation technique is complete progressively too, create conditions for solving the above-mentioned problem. Because of this technological development trend, this text has designed the fast pulse generator of a new kind of high pressure. Upper voltage, sharp pulse and high repeatability are the developing direction of the pulse power device. High frequency is an effective way of reducing the systematic volume. Originally design adopting igbt as main switching element, it is 5kv to output the peak-to-peak value of pulse voltage, the frequency is adjustable for 1khz- 10khz, the pulse front edge is 200ns. 1 Adjustable high-voltage D. C. generator: We use the intersection of mains frequency and alternating current as power, in the intersection of undervoltage and part commutate and inverter circuit produce the intersection of undervoltage and pulse, passages through which vital energy...
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.....
