Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–ac inverter. This paper proposes a converter that employs a floating active switch to isolate energy from the PV panel when the ac module is OFF; this particular design protects installers and users fro...

An improved active snubber cell is proposed for ZVT-ZCT PWM DC-DC boost converter. Zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off is provided by this active snubber cell. There is no extra current or voltage stresses on the main switch. Also, zero current switching (ZCS) turn on ZCT turn off is provided for the auxiliary switch. Although there is no extra volta...

Today, the use of renewable energy sources is increasing. Photovoltaic systems are also among sources. These a direct current source and cannot produce when there no sunlight. In this study, performance analysis Hard Switching (HS) DC-DC boost converter Soft (SS) in literature with PID controller were performed on photovoltaic system. The converters, which simulated Matlab/Simulink software was...

One of the most promising forms renewable energy is solar energy. However, efficient exploitation this form a topic great interest, especially in obtaining maximum amount power from photovoltaic (PV) system under changing environmental conditions. To solve problem, it necessary to propose an optimal algorithm. Therefore, paper presents feasible point tracking (MPPT) technique for DC/DC boost co...

The inherent nature of normal boost converter has more voltage stress across the power electronics switch and ripple. The presented formation of the front end rectifier stage for a photovoltaic (PV) organization is mainly used to give the supply. Further increasing of the solar efficiency is achieved by connecting the zero voltage soft switching boost converter. The zero voltage boost converter...

Usually basic dc-dc boost converters are unable to provide high step up voltage gain due to the effect of power switches, rectifier diodes and equivalent series resistance of inductors and capacitors and the voltage stresses on the power switches are high. This paper proposes a simple transformerless dc-dc converters to achieve high step up voltage gain without an extremely high duty ratio. The...
