Ultracapacitors Utilization for Automotive Applications	2010	5	.pdf	application/pdf	2275	140	62	The ultracapacitor also has other advantages – it is capable of very fast charges and dis- charges, a millions of cycles without degradation, extremely low internal resistance or ESR, high output power, etc. Ultracapacitors cannot yet be used as a primary power source in automotive applications. Power losses of hard-switching vs. soft-switching Hard-switching is very widely used for power inverters, whereas soft-switching is used only in high frequency applications.	cache/ap-1153.pdf	txt/ap-1153.txt
