Abstract
Since the efficiency of conventional boost converters are limited by the presence of parasitic parameters of the components used and remarkable power loss, it is necessary to cascade impedance networks to achieve high voltage boost in the output. To obtain the desired voltage, boost converters can be connected in series which is, however, complicated due to additional switches and control units. The inclusion of additional switches and control units degrades the reliability of the system. A high-frequency isolation DC-DC converter with a high transformer turns ratio was applied to solve these problems, but due to weight of transformer, the whole circuit becomes bulky which increases the cost. In this proposed system, a fuzzy-based MPPT control is employed to track the maximum power output from the PV panel, and a microcontroller is employed to produce 100 kHz PWM pulses such that when the duty cycle increases, the voltage also increases.
