Recently, as the perception of eco-friendliness has changed, demand for energy storage devices been rapidly increasing due to growth electric vehicle industry and smart grid facilities, which are emerging an alternative next-generation electricity supply demand. Therefore, importance battery management technology is growing, various voltage balancing techniques between cells being studied in or...

This paper describes a multiphase pulse width modulation (MPWM) technique used for controlling the luminance of a solid-state lamp (SSL). In conventional pulse width modulation (PWM) and pulse code modulation techniques, the average HBLED string current is controlled by simultaneously varying the “ON” time duration of each current regulator circuit, resulting in large current transients and pul...

The Inertially Stabilized Rifle is a new stabilized rifle system that can eliminate the disturbances induced by the shooter. Recurve actuator is used in this system to provide the precise movement of the rifle barrel. In such a portable device, only low voltage electrical sources are available yet the piezoelectric actuator needs high voltage to drive the actuator. The actuators consume little ...

With the trend toward achieving high efficiency, power density and operating frequency in converters, a galvanic isolated circuit architecture is proposed this article for step-up applications with wide input-voltage range. This converter consists of current-fed resonant push-pull (PP) as dc transformer (dcX) dealing most efficiency an active clamp flyback (ACF) regulator within large conversio...
