Meeting ID: 376 777 009 960
Passcode: SjyDtg

Agenda:

• Kamran Daniel, "Load Current Harmonic Sensitivity of Energy Efficient Devices with AC/DC Power Converters". Supervisor: Prof. Lauri Kütt.

Designing high-power medium voltage conversion solutions is subject to many constraints and challenges, significantly different from many low-voltage applications. Nevertheless, design optimization can still yield high-efficiency designs combining readily available semiconductor devices and magnetic materials, supported by advanced control methods. The talk will discuss these challenges and provide illustrative examples from the past and ongoing research work conducted at the Power Electronics Laboratory at EPFL.   Read more
