reduction of total harmonic distortion in power inverters
... bus voltage. The distortion is more evident when using low dc bus voltages. As a result, motors driven by these inverters have important torque pulsations. This work proposes to reduce the distortion produced by dead times and voltage drops across the switches using a simple algorithm that recalcula ...

For the presence of the Cc2 with drain, the DC voltage component is present at the drain but has been removed from the output voltage at Vout node, because we have measured output at that node which is connected with a capacitor. This capacitor removed the DC part of voltage. The output terminal has ...

... Dimming LEDs You would think that it is just a case of reducing the voltage to dim an LED. If you simply reduce the voltage to a resistor-LED combination you will dim the LED, but an LED with a forward voltage of 2.2V will not begin to light up until there’s about 1.5V across it and the difference i ...

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.
