Switch on of electrolytic capacitor as no polarity

Switch on of electrolytic capacitor as no polarity

Often in the electrical engineering devices the no polarity capacitors of large capacity are used. Common no polarity capacitors are enough large. Switch on of electrolytic capacitors like on a picture enables to attain a necessary result. A current passes through the diode D1 to the capacitor plate C2 (+) from the positive semi wave , and in opposite direction a current passes through the diode D2 to the capacitor plate C1 (+) from the negative semi wave . A capacity (at such switching on) will be: C = C1 = C2. Capacitors must be chosen on nominal voltage, and diodes on a maximal current.
Polarity of capacitors can be changed through changing polarity of diodes.
