as already been replaced by the switching power supply; This text has introduced a kind of three phases inputting, anti exciting type stabilized voltage supply of switch of multi-output based on chip FSDM0565R of switching power supply. Have analyzed characteristic and operating principle of FSDM0565R, and provide its design circuit diagram, calculation of actual parameter and the choosing of the device, provide surveying the waveform and testing the technical indicator of this power module finally. Experimental result show, utilize switching power supply of chip design this have with high efficiency, the intersection of volume and little, the intersection of circuit and simple, the intersection of input voltage and the intersection of excursion and wide, the intersection of ripple and characteristic such as being little. Solve the problem that industry`s on-the-spot three phases input at the same time, have actual value to popularize. FSDM0565R is that the one piece switching power supply that Fairchild semiconductor produces designs the chip, it is shut off protective circuit, trouble protective circuit and other controlling circuit to integrate in a one piece device by PWM control device, Shaker, heat. Because own power consumption of the chip is very low, power efficiency is achievable about 80%. The concrete characteristic is as follows: A, firm internal avalanche value SenseFET; B, first intermittent for work pattern...
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.....
