This article describes the different modulation and control techniques that can be applied to converter topologies with bidirectional impedance networks for applications in tracction systems for ...

The mixers require an external LO signal and can be used as direct carrier quadrature modulator and demodulator to implement higher order quadrature amplitude modulation formats. The up-converter has ...
