In this report, it is formalized that common-mode voltages are excited by switching current flows on parasitic capacitor between a heat spreader of a MOSFET and a heat sink.
In order to control a coupling path of the common mode current, using a MOSFET whose source electrode is connected to a heat spreader for a lower switch of a half-bridge circuit reduces common-mode voltage up to about 30 MHz.
In addition, satisfying the impedance balance condition between the parasitic capacitance around the MOSFET and the parasitic inductance on the power and ground lines can also reduce common-mode voltage above 30 MHz.
According to SPICE simulation, changing the position of parasitic capacitance obtains 15-dB reduction of common-mode voltage below 100~MHz. |
