9. Implication of Micro-Inverter Architectures
 Dramatic Increase in Electronics Content
 Per Panel Sensing & Control now required
 Processor Required for each Panel
 Communications required between Panel and Central Unit
PLC, RF, CAN
 Significant Pressure on System Cost
 Requires Highly Optimized System Solution
Integrated Processor with ADCs, DSP, PWM Controller
 Harsher Environment for Components
 Components need to be reliable for 25 years
 Components are exposed to extreme Temperatures

12. Various Standards at Play
 IEC61727; Characteristics of the Utility Interface
 IEC62109; Safety of Static Inverters
 Comparable to UL1741
 IEC62116; Anti-islanding test procedures
 VDE 0126; Most important German safety standard
 Recently revised version now demands a Residual Current
Monitoring Unit (RCMU) for transformer-less inverter designs
 This RCMU must be capable of measuring any ac or dc residual
current flow
 Standard CTs cannot measure dc current so alternative current
sensing techniques are required
Energy Segment

13. Main Challenges & System Considerations
 Higher reliability and lower assembly/manufacturing costs
 Relatively harsh environment with temperatures of up to +125
 Power conversion efficiency is critical and need components
consume as little power as possible
 Keeping the generated harmonics below the regulatory levels
 Maintain low dc injection current levels onto the grid

14. Why Choose ADI?
 ADI’s expertise in integrated energy measurement—300
million ADI metrology-based meters deployed
 50% of all electrical grid equipment worldwide uses ADI
converters
 Precision measurement of current & voltage through highly
accurate converters and amplifiers
 Enabling power networks using high performance processing
technology engineered with robustness and reliability
 Mixed-signal conversion and processing enable ease of
design and reduced time to market

57. Goals of this Demonstration
 A platform to demonstrate energy conversion as applied to solar
photovoltaic (PV) and other alternative energy systems.
 A platform to demonstrate and develop algorithms, running on a BF506F
processor, central to the operation of an inverter and/or charge controller.
These modular algorithms include:
 Maximum power point tracking (MPPT).
 Ac current regulation.
 Ac voltage regulation.
 Anti-islanding.
 Dc bus voltage regulation.
 Communication to external devices.
 A platform to evaluate computational requirements placed on a BF506F
processor used for renewable energy applications.
 A platform to provide reference software and inverter hardware design
 Hardware BOMs, schematics and artwork provided with kit
 Firmware provided by Advanced Energy Conversion
 Some high level control code source will be available royalty free
 Key software functions considered intellectual property of AEC can be licensed
 Contact timothy.resker@analog.com for more details

58. PV Inverter Application Capabilities
 Boosting the voltage output by the solar PV panel into a sufficiently
high voltage to allow for inversion into either a 120V (rms), 220V
(rms), or 240V (rms) utility voltage at either 50Hz or 60Hz.
 Using the bidirectional dc/dc converter for maximum power point
tracking (MPPT) of the solar panel output.
 Operating the bidirectional dc/dc converter in reverse to deliver
energy to the dc input, as in battery charging.
 Inverter operation for either output current regulation or output
voltage regulation.
 Using the single-phase inverter as a buck converter to support
battery charging.
 Aggregating energy from multiple sources into a common dc bus
before inversion into the utility.
 Operation with a fixed or variable dc bus voltage. Regulation of the
dc bus voltage can be accomplished through either the bidirectional
dc/dc converter, or the single-phase inverter.
