RB converter. Manual of the I/O expansion modules. „ Those manuals are available on WEG website - www.weg.net. 2.2 TERMS AND DEFINITIONS USED IN THE MANUAL Regenerative Frequency Converter: three-phase switched boost-type converter that converts alternating voltage (AC) of the grid into DC voltage (DC Link). It can absorb energy from the grid (AC) or return energy to it, being used as a DC voltage supply that feeds one or more output inverters.
Page 9 General Information DC-: Negative terminal of the DC Link. Arm U, V and W: Conjunto de dois IGBTs das fases U, V e W de entrada do conversor regenerativo. IGBT: Insulated Gate Bipolar Transistor: it is a basic component of the U, V and W arms. It operates like an electronic switch in the saturated mode (closed switch) and cut off mode (open switch).
