Efficiency can be calculated by dividing the output power by the input power. So if the output power is the same as the input power then efficiency is 100% and the regulator wastes no power. This is the ideal, but … Continue reading →

How do you build a power supply for a circuit? The formula used to determine the AC voltage required from the transformer is as follows: Vdc= Output voltage. Vreg=Voltage drop of the regulator =3v. Vrec=Voltage drop across diodes=1.25V. Vrip=Ripple voltage=10% … Continue reading →

Simply put, a modular PSU allows the builder to attach (or detach) cables as they’re needed. Traditional power supplies, on the other hand, have the cables attached permanently to the PSU. What is non modular PSU? A non-modular PSU comes … Continue reading →

What is the power output from a computer USB port? Most computer USB ports supply 5V of electricity with a maximum current of 0.5A. This amount of current is standard across the majority of computers and means the overall power … Continue reading →
