INTRODUCTION
Static converters, like direct-current machines (dcms), are a fundamental link in variable-speed drive systems. Static converters for DCMs are very specific and can be classified into two main families:
that operating from the alternating current network;
that supplied by a DC voltage source, possibly created by rectification from the mains.
This article describes the main reversible and non-reversible structures, their static characteristics and their dynamic modeling.
Discontinuous conduction phenomena highlight a strong coupling between the machine and the converter, leading to non-linearities that are mentioned but not dealt with here.
Finally, the main architectures of the current and speed control structures of these variable-speed drives are presented.
