Power diode - Circuitos electrónicos

So, this is a little project I did almost in the middle of my exam period, which finished a week ago. It is basically a substitution of a thermostat, regulating heating appliances in an apartment. It is web controlled and monitored, and works in auto and manual mode. It consists of an Arduino (Duemilanove), an Arduino Ethernet Shield, a temperature s.......

In this post we study an outstanding high current diode which features not only an in-built reverse current protection but also an overvoltage protection for safeguarding sensitive electronic circuits against back emfs, transients and load dump occurrences. The device RBO40-40G/T from STMicroelectronics comes in a TO-220 package and looks quite like a power transistor, however practically it's designed to work like a rectifier diode rated at a high 40 Amps. Th.......

Solar Power Center and Solar Charger CircuitTLC2272 - 10 Amp out Solar Power CenterThe SPC3 is a solar power center, it can handle all of the power functions for a solar charged 12 Volt DC system. The SPC3 contains a 9 amp photovoltaic charge controller, a 10 amp low voltage load disconnect circuit and a built-in white LED array for area illumination. The low voltage disconnect circuit has a load on-off switch, and a battery low voltage indicator. By using the SPC3 as the center of a solar power.......

Here the low power 12V transformerless power supply circuit with full-wave rectification. A lot of circuits could be powered straightaway in the electric mains using the support of a series capacitor (C1). The problem with this method is the fact that typically only one half cycle of the mains wave-form can be used to deliver a DC voltage. An obvious option is to wo.......

In many small or large industry, you may have seen such a lot of fan that speed is control according to temperature of the place. Thus during this article we have present a demo of that application. It's assume that you have an idea to how to read reading from the temperature sensor IC. In industry temperature range will be more than 100 oC but here we will work on very low range. Required Components Arduino UNO board (buy from here arduino

IntroductionThere are varieties of digital temperature logger projects available online based on different microcontrollers. The one I am going to talk about is based on a Microchip's 8-pin microcontroller, PIC12F683. It reads temperature values from a DS1820 digital sensor and stores in its internal EEPROM. PIC12F683 has 256 bytes of internal EEPROM and we are going to store the temperature values in 8-bit format. This means only the eight most significant bits of temperature data from DS1820 w.......

There are two main pages in this section of the web site; How to derate Transistors by Temperature [Power x Temperature], and Diode Derating [Current x Temperature]. An interrelated page details how to read and Interpret Temperature Derating Curves, which works for diodes or transistors. One of the new pages covers component mounting consideration, as Lead Length vs Thermal Resistance [power dissipation for leaded parts]. This particular topic shows why lead length is an important consideration .......

I was reminded this morning of a LED flasher I designed, which literally ran off "thin air", and caused quite a splash at the time. Here it is (pictured). Note that it is Copyright © Wimborne -- I have special permission to show it here (it also appears in my book). It is in two parts, which are wired together as shown: a diode pump (top), and a flasher (bottom). Wi.......

Due to the low current drawing, the circuit can be supplied from 230Vac mains without a transformer. Supply voltage is reduced to 12Vdc by means of C1 reactance, a two diode rectifier cell D1 & D2 and Zener diode D3. IC1A, IC1B, R2, R3 and C3 form a reliable bounce-free toggle switch operated by P1. R4 and C4, wired to pin #6 of IC1B reset the circuit (lamp off) when power supply is applied. IC1C and IC1D wired in parallel act as a buffer, driving the Gate of the Triac through R5........

Solar panels usually include a diode at their outputs. The diode prevents current from back feeding into the panel at night from the battery being charged by the panel. But, this diode does waste some power and does reduce the available panel voltage.  To reduce both the power and the voltage drop to a low level, Solar panels usually include a diode at their........
