Providing a transformer for an inverter |
摘要 |
In one embodiment, a transformer is provided for coupling between a utility connection and a plurality of power cells of a drive system. The transformer may be of a horizontal arrangement and include a housing and a core configured within the housing and having multiple columns each adapted along a horizontal axis. Each column corresponds to a phase, and each phase includes a coil having primary winding and multiple secondary windings concentrically adapted about the column horizontal axis to provide an air gap between adjacent ones of the primary and secondary windings. In addition, the transformer may include a baffler adapted about the core and configured within the housing to prevent air flow at a periphery of the coils and to direct air flow through the air gaps of the coils. |
