| Abstract |
This paper presents a current sensor with a wide bandwidth from DC up to around 250 MHz tomeasure fast commutation currents in power electronics. The sensor consists of a coaxial housing andit is inserted into the current conducting path. The inserted inductance into the commutation loop isaround 1 nH, which is achieved by the coaxially designed housing of the current sensor. The magneticfield capture is based on TMR sensors and a Rogowski coil, which are combined by the HOKAprinciple. |
