The evaluation results for the normal mode and common mode
of the SiC inverter prototype that are shown in Figure 1 are described here.
From Table 2, it can be observed that there are 10 kinds of values, including [+ or -][V.sub.DC]/2, [+ or -]7[V.sub.DC]/18, [+ or - ]5[V.sub.DC]/18, [+ or -][V.sub.DC]/6, and [+ or -][V.sub.DC]/18 regarding the common mode
voltage of the NNPC inverter.
Furthermore, no matching condition of passive elements is required, the filter features high input impedance and high common mode
On the other hand, there is no device used to cut down the noise in the common mode
The common mode
noise enters into the medical equipment through lines and returns back via the chassis ground, wherein, the differential mode noise couples between the lines.
There are two mechanisms by which this common mode
current can be induced on the cable: current-driven (magnetic field coupling) and voltagedriven (electric field coupling) .
In this letter, a wideband differential bandpass filter (BPF) with differential mode passband and common mode
suppression is proposed and implemented on microstrip lines for wideband application.
Thus, in its differential mode of operation, the antenna operates over a frequency band that is complementary and (more importantly) below that of the common mode
. Thus, by appropriately combining these two modes, the lowest frequency of operation of a coupled loop antenna can be reduced significantly, without increasing its occupied volume.
Even mode impedance mismatch with 50 [OMEGA], mismatching benefit to suppress common mode
noise, the DGS of Sections 2 and 3 suppress mainly common mode
Further, several applications have demonstrated that the new Z2 Syncarb performs exceptionally well in zinc distillation operations where a common mode
of crucible failure is corrosive attack from zinc vapors.
Test for immunity to conducted, common mode
disturbances in the frequency range 0 Hz to 150 kHz.
Additionally, Fairchild said that the FOD8012 supports communications of digital signals between systems without conducting ground loops or hazardous voltages and also features a switching speed of up to 15Mbit/sec using its proprietary Optoplanar packaging technology and optimized IC design to achieve common mode
rejection (CMR) of 20kV/[micro sign]s minimum providing noise immunity and extended temperature range of -40 to +110*C and a 3.3V or 5V supply voltage for logic level translation.
