Abstract:

Traditionally supercapacitors are used as energy storage devices replacing or hybridizing with batteries Typical applications include UPS power quality enhancers automotive electric vehicles and portable devices However if a super capacitor is treated as a device with a million times higher capacitance they can be used in different application domains such as high efficiency linear DC DC converters surge absorbers LED lighting systems and inverters with completely new design approaches These supercapacitor assisted SCA techniques use the two essential properties of an ideal supercapacitor i very long time constant and or ii performances as lossless voltage droppers This paper presents a summary of Supercapacitor Assisted Loss Management SCALoM as the underlying basis for high efficiency converters and protection systems such as the SCA low dropout SCALDO regulator SCA surge absorber SCASA and others An important property of SCALDO is high efficiency at a very low frequency with DC UPS capability SCASA is a high performance surge absorber with less component count than traditional protectors and with higher endurance to repeated high surges adhering to UL 1449 3rd Edition test procedure The paper will also show how SCALoM concept could be generally used in converters useful in renewable energy systems
