Modeling of Hybrid Ultra-capacitors for Power Electronic Applications Using PSPICE/ORCAD™

Hybrid ultra-capacitors are the integration of super capacitor and battery technologies. For performance improvement of a hybrid capacitor based system, accurate modeling is one of the requirements. Hybrid ultra-capacitor or Hybrid Capacitor (HUC) is modeled and then simulated from fundamental circuit of super capacitor with focus on leakage resistance parameter variation. Super Capacitor (SC) - MAXWELL^TM 100F is simulated in its 5^th order and simplified to 2nd order maintaining charge sustenance. All the simulations are performed for the first time in PSPICE/ORCAD^TM. The paper focuses on charging/ discharging capability of the model in time domain, such that the properties of high energy density, high power density and cycle life of the hybrid capacitors retain.
