6 FAQs about [How long can a high voltage switch store energy ]
How does energy storage affect a supercapacitor?
The simple energy calculation will fall short unless you take into account the details that impact available energy storage over the supercapacitor lifetime. In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume.
How long does it take to discharge a capacitor through a resistor?
Discharging via a resistor is exponential and theoretically takes forever. The ideal discharge procedure is through a constant current, so that the voltage drops at a constant rate and the total discharge will end quickly.
How long does a capacitor retain its charge?
Capacitors have 'leakage resistors' that allow them to discharge over time. A big capacitor may hold a charge for some time, but you likely won't get much further than 1 day in ideal circumstances.
How do you know if a power supply has a high voltage?
To know if a power supply has high voltage, measure the capacitors in the mains power supply. These capacitors, especially those in the mains power supply, are the most suspicious and contain high voltages and high capacitance. If you're unsure, you can measure them to confirm.
How do I Optimize my energy storage system?
The key to optimizing a solution is careful selection of components so that holdup times are met, but the system is not overdesigned. That is, one must calculate the energy storage required to meet holdup/backup time requirements over the lifetime of the application, without excessive margin.
Which components in a PC power supply hold high voltages?
The capacitors in the mains power supply are the most suspicious, these contain high voltages and high capacitance. If you don't know for sure, measure them.
