The IGBT Protection

. Principio di funzionamento I primi IGBT erano tiristori modificati per potersi accendere con un comando in tensione. Consider the BJT equivalent circuit of a thyristor and a MOSFET transistor is added between the collector and emitter ...

Fast MOSFET Test

. Often in online discussion I find myself having to explain how a mosfet is head, the test with a multimeter is the fastest but, not from the certainty that the component functions properly in impulsive regime. Rummaging through the drawers ...

Fuel Cells

. Rechargeable batteries are not clearly enough to power electric cars for a considerable period of time. Without reliable and capacious batteries, you lose the challenge of mass mobility. So the industry is working ...

Albert Einstein and the GPS

. I'm a big fan of Albert Einstein. Many physicists would agree that his theories are the purest expression of genius in the history of humanity with all the ensuing applications. In this case, we talk about the Global ...

Control with Bluetooth Nano

With a bit 'of time available I thought of putting on a via bluetooth control. The thing is quite simple using those modules available on the market. I took a HC-06, It allows simple data communications ...

Movement controlled encoder

Descrizione Semplice controllo di rotazione con motoriduttore che ha un encoder a due fasi montato sull’albero del motorino elettrico. During the tests I burned the 16F84A I had and for this I used a 16F628A. The program…

Pressure Recorder (datalogger)

I was asked to help develop a program that controlled the pressure and would record on file. The project is an assembly of some of the Arduino module to demonstrate the proper result of the program, as requested. Descrizione Questo…

Generatore onde box

This is a simple assembly of some component that I have in the drawers. I got an Arduino UNO r3 and a LCD display with some electronic component, because I need to simulate an encoder. In addition I have also written in the program ...

non-invasive test for injectors

. Now all engines have injectors for fuel, they are managed electronically by a control unit, which decides the injection time or the time for which the injector must remain open and therefore the amount ...

TRIODES ELECTRONIC

TRIODI ELETTRONICI Questo articolo sarà dedicato ad un altro tipo di tubo elettronico, the TRIODE, that can be compared to a faucet, since it allows to vary the current flowing through it, precisely like a tap makes it possible to adjust ...
