A PORTABLE SOLAR POWER SUPPLY DEVICE WITH HIGH-EFFICIENCY INVERTER
A portable solar power supply device with high-efficiency inverter was developed. There are several design principles and effective approaches of the device were discussed in this paper. It is necessary to integrate the pure sine-wave inverter with a DC converter in a single compact enclosure for mobile applications. Adopting MPPT technique in DC converter can optimize the output of the solar modules. The patented circuit of pulse formation and distribution in SPWM help to simplify the inverter structure and reduce its made costs. Using the nano-crystalline-core transformer and SMD can compact the inverter size and reduce power self-consumption. Optimizing the EMC design is important to control the electro-magnetic interference of the inverter. The portable solar power supply device described above is high efficiency, less output waveform distortion, small size, light weight, and lower cost.
