The cost is undisputedly the most important parameter which influences the commercial success of any product. The idea here is, however, not directly to reduce costs, but to make the best compromise. Increase in costs must be weighed with respect to the payback period (due to better efficiency), decrease in system costs, Real estate costs and other logistics.Also, In some cases, the cost is reasonably reduced by the use of control strategies, specific to each topology.
Application specific requirements:
Some of the installations feed into a medium voltage (10kV) grid, while others feed into a low voltage (400V) grid. The solution, which suits one configuration, is not the best option for the other configuration. Therefore, there is a need to identify optimal solutions for both cases. Last but not the least, the solutions must confine to the various agency norms.
