I want to use a 1.5 F super capacitor as the output capacitor in an audio range power supply regulator but I have a question about the cycle limits of supercapacitors.
Usually capacitors can be expected to last forever at low temperature but I guess supercapacitors have maximum charge/discharge cycles.
Let's say my wall voltage frequency is 50hz and I have a continuous sinewave of 10hz being pulsed from the capacitor into a load that draws 2 amps.
1.5F at 2 amps will last somewhere around 30 seconds in my power supply but the lowest expected frequency being 10hz that means it will only draw current in 100ms cycles and it will be charged every 20ms, so in reality it will lose almost no charge in between rectifier cycles.
Does this mean that it have to go through enough tiny discharges to amount to the equivalent of the maximum complete charge/discharge rating of the capacitor or does it mean it won't even count as a single charge/discharge?
