Bidirectional Converters F3E

The demand for regenerative IGBT "rectifiers" has led to the development of F3E and AFE bidirectional converters with rectifying capabilities and network recovery capacity.

The F3E bidirectional converter is a Fundamental frequency front-end regenerative unit - identified by the SDF code.

It's a regenerative power module solution where the AC/DC converter uses diodes inside the IGBT modules to supply the DC bus, while the IGBTs are used during regenerative operation.

SECOM has created a series of IGBT bidirectionals converters for these specific applications with particular attention to the development of converters in the 100kW-8MW range at 400 and 690Vac.

The main advantages of using F3E regenerative power supplies are:

Economic advantages of a low cost regenerative system

High module power density, thanks to the low module losses.

Further cost reduction of the filter (three-phase inductance), compared to the LCL filter for AFE system

Modular wheeled-mounted system for easy installation and maintenance.
