A solar panel emulator is a programmable power supply which mimics the characteristics of a solar panel and can be used under laboratory conditions. This paper proposes the design of an economical solar panel emulator using LabView software and its implementation using Arduino. The proposed emulator consists of a flyback converter with a MOSFET driver which brings out the characteristics of the desired PV panel. The characteristic curves are generated using LabView software and PWM signal is generated in hardware. This PWM signal drives the MOSFET which in turn operates the flyback converter. The proposed system is simulated using MATLAB software and a prototype of the proposed system is implemented using Arduino UNO R3.

RCC circuit (self-oscillating flyback converter) is a kind of high efficient working circuit by use of several devices, but excessive control current will cause the occur of intermittent oscillation. And then the oscillation frequency of the circuit change in a large scope (from hundreds of hertz to several thousand hertz). In addition, the output power is more likely to make the transformer device to produce abnormal noise. However, this phenomenon is not completely useless. After improving the RCC circuit can be conclude that the circuit can start in applying a pulse signal if the output power is small. The switch circuit operates in low-power state by means of intermittent oscillation. The result is that RCC circuit have high performance price ratio and low cost, so it is a widely used in high performance power supply equipment.
