Performance Analysis of Solar Based High Step-Up DC-DC Converter with Various Filters

This paper proposes a converter that employs a proper filter to the load. This particular design protects installers and users from electrical hazards. Exclusive of extreme duty ratios and the frequent turns-ratios of a coupled inductor, this converter achieves a high step-up voltage-conversion ratio; the leakage inductor energy of the coupled inductor is efficiently recycled to the load. These features explain the module's high-efficiency performance. The detailed operating principles and steady-state analyses of continuous, discontinuous, and boundary conduction modes are described.
