Delay

Image
An Inverter Delay(up to 10sec)  Delay is one of the most essential part of power circuits. Focusing more on power inverter, the role of delay is to allow the oscillating system shutdown completely before the transformer receives charging input. When the oscillating system is not properly shutdown this can cause lot of damage to the inverter circuit; damaging of the oscillating system and MOSFETs. The Circuit The delay circuit can work with any DC in which you will have play around with the R1, variable resistor, capacitor and the zener diode. The higher the capacitance of the capacitor the longer the time (even though it can be adjusted using the variable resistor) Questions and view in the comment box For free PCB send your email

What's the difference between DC and AC electricity?

When we think of electricity as a flow of electrons, we're usually picturing DC (direct current) in our minds. In bigger household appliances, electricity works a different way. The power supply that comes from the outlet in your wall is based on alternating current (AC), where the electricity switches direction around 50–60 times each second (in other words, at a frequency of 50–60 Hz). It can be hard to understand how AC delivers energy when it's constantly changing its mind about where it's going! If the electrons coming out of your wall outlet get, let's say, a few millimeters down the cable then have to reverse direction and go back again, how do they ever get to the lamp on your table to make it light up? The answer is actually quite simple. Imagine the cables running between the lamp and the wall packed full of electrons. When you flick on the switch, all the electrons filling the cable vibrate back and forth in the lamp's filament—and that rapid s...
