Abstract
An invention that reduces an influence of dv/dt noise generated by power switching elements around a Rogowski current sensor. By separating a coil into two coils and connecting voltages generated from the two coils in series in a reverse direction, a total amount of parasitic capacitance is reduced by ¼, and accordingly, Cp*dv/dt noise is reduced. The Rogowski sensor including a first coil (Coil-P) which detects a portion of a switching current passing through bus bars (a,b) and includes a first end and a second end, and a second coil (Coil-N), as a coil separated from the first coil, which detects a portion of the switching current passing through the bus bar and includes a first end and a second end, wherein the second end of the first coil is connected to the second end of the second coil to form a neutral point ().
