4. Anti-Interference Equipment – Input Filters

... To limit input current spectrum, an input reactor may be used. The reactor also extends conducting time of rectifier diodes. Thanks to extended conducting time, the loading of the diodes gets lower. The reactor is necessary in case of high short-circuit power of the mains (at least 10 times converte ...

The output voltage cannot go below the internal reference voltage, and internal circuit operation may limit the minimum ON time and maximum duty cycle. Additionally, real-world circuits contain losses. These losses can act to e ...

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.
