Initially SCR2 is triggered to charge the capacitor through the load. Once the capacitor has charged up to the supply voltage SCR2 will turn off when current drops below its holding current.
In the right direction the capacitor doesn´t pass current, because the insulating layer between the two plates is intact, so no current can flow through it. When you reverse the voltage the insulating layer dissolves and the current can get from one plate to the other, discharging the stored charge and becoming a short.
AC or bipolar electrolytic capacitors have two anodes connected in reverse polarity. DC electrolytic capacitors are polarized by the manufacturing process and therefore can only be operated with DC voltage. Voltages with reverse polarity, or voltage or ripple current higher than specified can destroy the dielectric and the capacitor.
The effect of reversal on a particular capacitor varies with the design of the capacitor, the voltage at which it is being operated, the temperature, the pulse repetition rate, and other factors.
I was going through the working of class D commutation and the article said: As soon as the capacitor completely discharges, its polarities will be reversed but due to the presence of diode the reverse discharge is not possible. Why does the polarity of the capacitor reverse as soon as it completely discharges?
The voltage on a capacitor is not the rating, but rather how much voltage you can expose the capacitor to. For example, if your voltage source is 9 volts, you should choose a capacitor that is at least double the voltage, 18 volts or even 27 volts to be safe. AC or bipolar electrolytic capacitors have two anodes connected in reverse polarity.
Polarized capacitors can be connected in reverse polarity by adding a DC bias of at least half the AC peak-peak voltage. This way, the entire signal is still positive, but AC-wise the capacitor acts on it normally. In reverse polarity, polarized capacitors are mostly used for bulk storage on power supplies to reduce ripple and to provide short term high current.
