As low voltage microcontrollers have proliferated, there are times where external devices need to be driven by a higher voltage. A simple level shifter can solve this problem. Not only can it drive higher voltages, but with a simple analog filter, this can be used to provide a variable voltage...

Power Factor Correction is a technique which uses capacitors to reduce the reactive power component of an AC circuit in order to improve its eficiency and reduce current. When dealing with direct current (DC) circuits, the power dissipated by the connected load is simply calculated as the...

Transformer Voltage Regulation We have seen in this series of turorials about the transformer, that when the primary winding of a transformer is energised, it produces a secondary voltage and current at an amount determined by the transformers turns ratio, (TR). So if a single-phase...

An FET constant current source is a type of active circuit which uses a Field Effect Transistor to supply a constant amount of current to a circuit. But why would you want a constant current? Constant current sources and current sinks, (a current sink is the reverse of a current source) are a...
