Abstract
A high-frequency noise absorbing circuit in a control circuit of a loading device having a power supply section (I), a converter circuit section (II), a DC link section (III) and an inverter circuit section IV, with capacitors C3 and C4 being connected between ground and respective positive and negative terminals of the DC link section (III) and a smoothing capacitor C1 connected between the positive and negative terminals of the DC link section (III). The high-frequency noise absorbing circuit includes a zero-phase reactor L1 arranged in the power supply section (I). Further, the high-frequency noise absorbing circuit includes a zero-phase reactor L1 arranged in the power supply section (I), and capacitors C5 arranged between the lines of the power supply section (I).
