6 FAQs about [Super Pulse Load Capacitor]

Are supercapacitors suitable for pulse power applications?

Supercapacitors are ideally suited for pulse power applications, due to the fact the energy storage is not a chemical reaction, the charge/discharge behavior of the supercapacitor is efficient. Supercapacitors are utilized as temporary energy sources in many applications where immediate power availability may be interrupted.

What are high power supercapacitors?

High power supercapacitors are designed similar to electrolytic capacitors however supercapacitors use high surface area carbon for accumulation of charge as opposed to the low surface area foils in electrolytic capacitors. An electric double layer is formed at the interface of the solid carbon electrode and liquid electrolyte.

What is the maximum voltage of a super capacitor?

The maximum voltage of a single layer super capacitor is typically 2.7 V, which leads to a usable capacitor voltage range of 1.9 V to 2.7 V. Figure 3 shows the basic flow of a recharge cycle. Most of the time the voltage is kept at 1.9 V to minimize the losses of the micro-controller and other leakage currents in the application (Phase 1).

What happens if a supercapacitor is connected across a supply?

When connected across the supply, they provide much of the energy needed by each load pulse, reducing voltage ripple and instantaneous supply current. However, supercapacitors draw a high charging current when first connected. This can cause damage to a battery, or cause the supply voltage in a host device to drop from current overload.

What is the difference between a supercapacitor and a current limit?

The current limit value is independent of the supercapacitor value and only depends on the maximum current the source can supply. The circuit in Fig 1 monitors the current by comparing the voltage drop across sense resistor (R6) with a reference voltage derived from a voltage reference IC (REF1).

What are the current requirements for pulsed discharge capacitors?

When defining current requirements for pulsed discharge capacitors, it is necessary to consider both the normal and fault condi-tions. If the fault current can be limited to about 10% of the shots and 3 times the nor-mal peak current, the normal conditions will drive the capacitor design.
