The two final power of TR2-TR4 should be mounted on heatsink the right size, otherwise they will overheat. You can choose from MJ4033 MJ3007 or more, provided that the NPN. The maximum power output that can be used depending on the size of the core of the transformer T1, the VA is: with 50 VA can be taken in the secondary 230 V 0. 2 A (current

consumed by the end will be 4 A) with 90 VA can be taken on the secondary 230 V 0. 4 a (current consumed by the end will be 7 A). The schematic diagram come from circuit: Converter 12 Vdc to 230 Vac or Inverter power supply. Go to that page to read the explanation about above power supply related circuit diagram. As shown in the Inverter circuit diagram obove, Its used as the oscillator stage astable multivibrator contained in IC1, a CMOS 4047 (this cult series 40xx series) by varying the resistance value of R1 trimmer (220 k total resistance). The above scheme is a motorcycle battery charger, which is intended only for charging motorcycle batteries as its has a low charge current and thereby saving the battery plate from premature failure. This motorcycle battery charger circuit generate current of. The Isolated Power supply 5 V to 15 V, 500 mA diagram represents a single control block, knowing that all are identical. It is truly classic, and is based on the use of common components. The Isolated Power supply 5. This Simple switching power supply for 15 Watt can be used to power any load up to 15. 20 watts and has smaller dimensions than a similar, but with the step-down transformer, operating at a frequency of 50 Hz. . This DC power supply circuit diagram is designed as an additional or as a permanent power supply for all general circuits based on a stable DC voltage between 3 and 30V provided that current consumption...
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.....
