Model F3E -Bidirectional Converters

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.
