Versatile distribution transformer
First Claim
1. A distribution transformer having a primary side for receiving input voltage and current from a source and a secondary side for providing output voltage and current to a load, the distribution transformer comprising:
- a ferromagnetic core;
at least one winding structure, each winding structure comprising a primary winding for connection to the source and a secondary winding for connection to the load;
a pocket defining a cavity and having connectors electrically connected to the at least one winding structure, the connectors being disposed in the cavity;
a power electronic module operable to reduce variations in the output voltage of the distribution transformer, the power electronic module being removably mounted in the cavity of the pocket, the power electronic module comprising a plurality of semiconductor switching devices and a plurality of connectors adapted to slidably engage the connectors of the pocket, the power electronic module being movable between a removed position, wherein the power electronic module is located outside the pocket, and an installed position, wherein the power electronic module is disposed in the cavity of the pocket and the connectors of the power electronic module engage the connectors of the pocket so as to electrically connect the power electronic module to the at least one winding structure.

Abstract
A versatile distribution transformer having an electromagnetic transformer and a power electronic module is provided. A pocket having connectors electrically connected to at least one winding structure of the electromagnetic transformer is mounted above the electromagnetic transformer. The power electronic module is removably mounted in a cavity of the pocket. The power electronic module includes a plurality of semiconductor switching devices and a plurality of connectors adapted to slidably engage the connectors of the pocket. The power electronic module is movable between a removed position, wherein the power electronic module is located outside the pocket, and an installed position, wherein the power electronic module is disposed in the cavity of the pocket and the connectors of the power electronic module engage the connectors of the pocket so as to electrically connect the power electronic module to the at least one winding structure.
