... voltage in BP585 PV panels is near to 19 V, hence such DC-DC converters do not operate since its output voltages are higher than the input voltages. Therefore, the mismatched panels delivers even less power to the load and the associated DC-DC converters have lower output voltage, which further incr ...

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.
