There is the alternative option of indirect energy conversion by employing the Indirect Matrix Converter (Fig. 5) or the Sparse matrix converter which was invented by Prof. Johann W. Kolar from the ETH Zurich. As with the DC-link based VSI and CSI controllers (Fig. 2 and Fig. 3), separate stages are provided for voltage and current conversion, but the DC-link has no intermediate storage element. Generally, by employing matrix converters, the storage element in the DC-link is eliminated at the cost of a larger number of semiconductors. Matrix converters are often seen as a future concept for variable speed drives technology, but despite intensive research over the decades they have until now only achieved low industrial penetration. However, citing recent availability of low-cost, high performance semiconductors, one larger drive manufacturer has over past few years been actively promoting matrix converters. [11]

Our Embedded AC-DC solutions provide customers ready to evaluate circuit boards for use in external adapters, open-frame power supplies, internal power supplies used in high end consumer equipment, and custom-built power supplies for specialized equipment. These solutions enable customers to design hardware that meets ENERGY STAR, California Energy Commission (CEC) and DOE Standards energy efficiency norms while allowing multiple configurable outputs, optimal overall efficiency, highly efficient low power modes (green mode), and built-in fault protections for user safety.
