– In this paper, a single-switch ZVZCS quasi-resonant CLL isolated DC-DC converter for driving a low-ower (less than 100 W) 32 " LED backlighting liquid crystal display television (LCD TV) is proposed. The proposed converter exhibits both forward and flyback operational characteristics. All semiconductors are activated and deactivated under the soft(More)
This paper proposes critical load following back-up system using MCFC stack. This system enables MCFC generation system to supply power to critical load without UPS and to generate rated power under grid fault state. This back-up system includes `Load Leveler' that is connected with 3-phase inverter and is controlled by additional algorithm that includes(More)
