Increased component integration is essential for new power circuit platforms to decrease cost and size, and increase efficiency and reliability. A 300 W four quadrant (4Q) photo-voltaic grid-tied micro-inverter using two new ASICs (Application Specific Integrated Circuits) was built and characterized. This inverter incorporates maximum power point tracking and dynamically operates throughout a power...
Power integration in power electronic circuits is important for new circuit designs since it tends to decrease the bill of materials, cost, and size of an application, with the added benefit of an increase in reliability. A functional description of a novel architecture called a Micro-Inverter Controller (IXC64) integrated circuit is discussed. The IXC64 has a 32-bit RISC microcontroller core with...
Integration of functions and features into silicon circuits is very important for a new power circuit design in order to reduce the electronic bill of material's (eBOM) cost and component count. These eBOM reductions increase the reliability and decrease the cost and size of a product. A low cost power micro-inverter using two application specific integrated circuits, analog power manager (APM) and...
High level IC integration in power electronic circuits is increasingly important for new circuit designs. This integration is essential in order to decrease the components used which inherently increases the reliability and decreases the cost and size of an application. A functional description and fully characterized test results of a novel architecture called an Analog Power Manager (APM) integrated...
This work targets modular nanogrids for remote locations, where photovoltaic modules can be gradually introduced to grow the renewable energy capacity at minimal capital cost, while reducing diesel fuel consumption. Today's grid-tied micro-inverters provide a modular solution for ac power generation in nanogrids but battery storage remains centralized, requiring an additional ac-dc converter. The...
