... between 40 and 75 volts. The Power Supply Let us settle on a nominal 50 volts. To obtain this from our 230v RMS mains supply we need to use a transformer. This is essentially a device which magnetically couples two or more coils of insulated copper wire wound around a common iron core. The mains sup ...

... It is common practice for the wires in the cables associated with garden lights to carry only lowvoltages (often 12 VRMS). However it is more efficient to use 240-volt globes in the lights. In order to achieve this, the circuit shown below is used. At the 240-V supply, the voltage is stepped down us ...

Six Channel SiC MOSFET Driver Features
... Each of the six gate drive channels is protected by a desaturation circuit. In the event of a short circuit, the voltage across the MOSFET (VDS) rises until it hits a threshold which causes the desaturation circuit to drive all six gate drive channels to their off state. Pin 17 of the 26 pin main si ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
