Future Energy Solutions demonstrates micro-inverter reference design at InterSolar 2011
June 10, 2011 // Paul Buckley
Future Energy Solutions is demonstrating a micro-inverter reference design board at the InterSolar 2011 exhibition, which aims to provide a model for the rapid development of highly efficient and reliable micro-inverter end products. The reference design is suitable for micro-inverters serving Photovoltaic (PV) solar panel arrays rated up to 200 W and comprising up to 72 cells.
The system is comprised of two boards: a controller board which features the 16-bit MC56F8257 digital signal controller from Freescale, and an inverter board which includes the DC-DC boost and DC-AC inverter stages and an auxiliary power supply. Customers can use the boards as a development platform to which they can easily add peripheral features such as a display screen, user interface and communications. They can also source the original design files from Future Electronics and modify them freely.
The design has adopted a non-isolating topology consisting of a DC-DC boost stage followed by a DC-AC inverter. Its omission of an isolating transformer, normally found in existing micro-inverter designs, helps to reduce losses markedly during power conversion.
The topology allows only a small 50 Hz ripple current to be reflected back from the 240 V AC load to the PV solar panel. The ripple current and ripple voltage are used to implement a fast MPPT technique called ripple correlation control, which is an effective means for capturing the maximum possible power from the PV solar panel throughout the hours of daylight.
Improvements over conventional micro-inverter designs have addressed durability issues as well as efficacy. The micro-inverter was designed from the outset to achieve long-term reliability both through significant derating of components, and through avoiding the use of life-limited aluminium electrolytic capacitors.All news
