Thermal runaway scares the heck out of many people; especially those that do not know how to detect that the conditions are being set for a thermal runaway. While thermal runaway can occur in most battery chemistries such as lead acid either VLA or VRLA, or Ni-Cad, or Lithium Ion, this paper is going to restrict itself to the VRLA technology.
This paper describes a molded-cased circuit breaker (MCCB) for higher voltage direct current (HVDC) power feeding systems. To protect circuits from fault current, such as an overcurrent or a short circuit current, an overcurrent circuit breaker is installed in power feeding systems. When a large-scale overcurrent circuit breaker is required, the case which uses MCCBs in HVDC power feeding system can...
This paper discusses the operating characteristics of push-pull type series resonant converter. The AC equivalent model and AC analysis of push-pull type series resonant converter are confirmed by analytically and experimentally. Moreover, the operating characteristics of push-pull type series resonant converter including SR are also investigated.
This work reports the results obtained using the SEPIC converter as an MPPT (Maximum Power Point Tracker) interface for photovoltaic systems employing a single voltage sensor. The MPPT algorithm is based on the variation of the input static characteristic impedance of a SEPIC converter fed by a photovoltaic panel. Although the SEPIC input impedance theoretically depends on its load resistance, it...
