Three-phase converters are common in modern power systems in interfacing of renewable sources and for improving power quality. A three-phase converter, whether operating as an inverter or active front-end, produces a varying common-mode voltage when conventional sinusoidal PWM is used. Frequency components of the common-mode voltage are located at the switching frequency which ranges usually from...
This paper presents a current sensor embedded in a laminated bus bar. The proposed sensor is based on the Rogowski coil principle and it can detect the magnetic flux corresponding to a derivative waveform of the current within the bus bars. The frequency characteristics of the current sensor including the parasitic parameters depending on the circuit geometry are discussed. After the design of the...
Newly developed 15 kV silicon carbide (SiC) power MOSFETs with fast switching capability enable the reduction of size, weight and complexity of medium voltage power converters. In medium voltage and high frequency applications, zero voltage switching (ZVS) is necessary since significant amount of energy is stored in MOSFETs' parasitic output capacitors. Recovering these energy is important for high...
