Technical FAQs 4

Is a supercapacitor a good backup power solution?

Once limited to mission-critical devices, backup power solutions are now in demand for a wide range of electronics applications in industrial, commercial, and consumer end-products. While there are several options, the supercapacitor offers the most compact and energy-dense solution as an energy reservoir when the main supply is interrupted.

How much power does a supercapacitor need?

This design provides an efficient method to extract maximum energy from a supercapacitor, and provides the required voltage and current to the RF subsystem. GPRS or GSM systems need peak currents of up to 2 A for several 100 us. LTE transmissions require peak currents of up to 1 A.

Can a diode power a supercapacitor?

Diodes allow either the primary power source or the supercapacitor to power the system (Figure 5). Figure 5: Using a single supercapacitor in a power backup circuit eliminates the need for cell balancing but requires a step-up regulator to boost the supercapacitor’s output voltage.

Are supercapacitors better than batteries?

Moreover, supercapacitors have much lower effective series resistance (ESR) than batteries. This allows them to provide power more efficiently without any danger of overheating. Supercapacitor power conversion efficacy of greater than 98% is typical.
