Design and make and measure, reveal the circuit of the output voltage of stabilized voltage supply, electric current, frequency and power of this frequency conversion, the error in emasurement is smaller than 5%. 1 Can use, produce SPWM Puls e-width modulation of sine wave Corrugate special purpose chip; 2 The output power can be calculated through the measured value of the electric current, voltage. Single-phase rectifying circuit: The following picture of choosing the rectifying circuit of single-phase half control is shown. This circuit control is flexible, the adjustable within the specific limits of the magnitude of output voltage, so become the selected scheme. But we find while finishing this part of a circuit. The flip flop of this circuit has certain difficulty. Under not making the situation that the rigid index stipulates to the rectifier while designing the index, we can well adopt the single-phase uncontrolled rectifying circuit, thus reduce the design of the flip flop of two triode thyristors. Originally design RC over voltage killer circuit R9, C5 adopted to connect in parallel in the second order of the voltage transformer Component side, In order to absorb the released energy of unshakable in one`s determination magnetic field of the voltage transformer. And change and store it for electric field energy of the capacitor, series resistance for consume some energy and inhibit the intersection of RC and...
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.....
