Power Converter Array

The Power Converter Array (PCA) is structured in layers of individual conversion cells connected together in series or in parallel as a network to meet the functional requirements. The cells are welded separately on each printed circuit board (PCB) assembled with metallic connectors. Each conversion cell is a Dual Active Bridge (DAB) DC/DC, AC/DC or DC/AC of a certain power, depending on the standard used. The power of the whole converter equals to the power of the DAB converter multiplied by the number of cells used. This singular design format is based on a technical innovation taken from the micro-electronic industry declined on a macro format. The architecture of the PCA allows to adjust the number of blocks to multiple usages requirements. The blocks can be reconfigured by cutting connectors after a first usage. They could be also used for a lower power conversion capacity in another system application where they would fit in.
