s a common misperception that electrolytic capacitors are the kiss of death for solid-state lighting reliability and lifetime. Not so: A properly de-rated electrolytic capacitor can work just fine for 10 years and beyond. (For more information, seeBurn out: Weak links affect HB-LED life...
The influence of deterioration, such as insulation, on the capacitor Calculation of 1.4.2 ripple current and temperature rise chart 6 shows that the heat generated by the ripple current is transmitted from the core package to the aluminum case The pathway to the external environment When a ripple...
Murata's polymer capacitor has the feature of low ESR, low impedance, and large scale. Furthermore, there is no DC bias characteristic of capacitance, and since temperature characteristics are also stable, it excels in the Ripple absorption, smoothness, and the transient response performance. ...
Unfortunately, the power electronic components required to drive LEDs are unable to compete with LED devices in terms of lifetime. Aluminum electrolytic capacitor (AEC) failures represent the root cause of power electronic equipment breakdown, mainly through both aging and temperature effects. This ...
The PO estimates the discharging circuit’s time constant based on voltage measurements, enabling the calculation of the capacitor’s parameters. Experimental results show that the proposed observer has faster error tracking than other methods, with the potential for real-time implementation due to its...
