“Solar cell module is about to enter a big change. For us to a large number of business opportunities.” Issue remark is that Texas Instruments (TI). The company in May 2009 set up a specialized solar cell business team. Changes in solar cell module is, the number of solar cell modules and the inverter is connected in series and then the way to the various modules in the inverter and converter with the way
Tandem solar cell systems are generally solar battery module, then for DC-AC converter with the inverter connection (shown in the “general system”). The new system is set in each module for DC-DC conversion converter, and inverter connections, or distributed configuration for each module inverter, so the system can improve the practical efficiency of solar cells. The map data according to the United States is drawn by Texas Instruments.
TI said that the way had a problem is if there is uneven due to sunshine and the characteristics of inequality lead to decreased output power module, the overall output power will be greatly reduced. To solve this problem, the scattered distribution inverter and converter. , Called “micro-inverters,” or “micro-converter” approach with each module output power by optimizing the output power to maximize the overall characteristics. In addition, the combination of communication, then, can be used to monitor the status of each module, the module detects the failure VGP-BPS9/B VGP-BPS9A .
Solar inverter can be said to be originally a collection of semiconductor devices (Figure 2). TI intends to use the advantages of technology companies increased for micro and micro-inverter converter product categories, including power output of each module to optimize the control IC, and the conditions for the delivery of each module of the communication IC.
Solar system is common inverter control circuit. Need to use a variety of semiconductors. The map drawn according to the information TI.
Power Transmission System voltage control circuit needs high-precision measurements. To meet the requirements and value of digital control, the need for sensors to provide data 16bit analog-digital conversion. The map data according to the letter is drawn by the United States.
Micro-Inverter Inverter features existing in the various modules with, from the optimization of output power to the DC-AC conversion by the module to carry out. Because the power output from the module to alternating current, direct access to power, so construction is easier. Expected to be installed on residential or commercial facilities, equipment, corporate existence of this need.
On the other hand, micro-converter output power of each module optimization and DC-DC converter, and the rest of the DC-AC converter is set by the other inverter to complete. As the solar cell module output power for the DC, it would have applied directly to the DC power into the rechargeable battery charge state purposes. For example, in areas without electricity and other wireless communications base station without access to grid facilities exist independent demand VGP-BPS9/S VGP-BPS13 .
