Aiming at the demerit of the traditional flux coupling driving circuit, an improved driving circuit is proposed which has some advantages, such as simple structure, low cost, the driving source isolated from the main circuit, etc. The proposed circuit can be used on the maximum power point tracking circuit of solar cell which has a wide range duty cycle. The circuit principle analysis is given. At last, experimental results are provided to verify its practicability.

Global Peak

Under partial shading conditions (PSC), most traditional maximum power point tracking (MPPT) techniques may not adopt GP (global peak). These strategies also often take a considerable amount of time to reach a full power point (MPP). Such obstacles can be eliminated by the use of metaheuristic strategies. This paper shows, in partial shading conditions, the MPPT technique for the photovoltaic system using the Bat Algorithm (BA). Simulations have been performed in the MATLAB ®/Simulink setting to verify the efficacy of the proposed method. In MPPT applications, the results of the simulations emphasize the precision of the proposed technique. The algorithm is also simple and efficient, on a low-cost microcontroller, it could be implemented. Hardwar in loop (HIL) validation is performed, with a Typhoon HIL 402 setup.

In order to address and meet the needs of people in these regions without electricity, we designed a small 500W off-grid PV-inverter. The main circuit includes battery charge and discharge circuit, and two-stage converter topology isolated. The digital processor TMS320F28023, high-performance and low-cost, is used to achieve maximum power point tracking (MPPT) of PV modules and charge control for battery. The experimental results of the prototype show that this design with high-precision and high-efficiency, meets the design requirements.
