For operating a Permanent Magnet Synchronous Machine (PMSM), which allows a highly compact design, you have to supply three-phase voltage with controllable output frequency and controllable voltage amplitude. There are many different alternatives for the AC/AC converter. Here you will learn all options.

• Part I - An Overview of AC/AC-Converter Topologies

You need a rectifier with sinusoidal input currents (power factor correction) and controlled DC-voltage at the output side? In this report you will learn how to compare the well-known Bidirectional 3-Phase AC/DC PWM Converter with Impressed Output Voltage (VSR) with a Vienna Rectifier employing a simple but effective strategy.
