EMIS has introduced the SMF911 and TMF911 series of single-phase and three-phase common mode facility power line filters, engineered to provide exceptional EMI and RFI suppression for industrial, ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...

Electrochemical capacitors, encompassing electric double-layer capacitors and pseudocapacitors, occupy a pivotal role in bridging the gap between batteries and conventional capacitors. Their high ...

A large majority of EMI problems, including both emissions and immunity, involve interference currents conducted into and out ...

A research team led by Prof. MENG Guowen from the Institute Solid State Physics, Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS), cooperating with Prof. WEI Bingqing ...

Seasoned equipment designers have long known that an EMC compliance “pass” on an end product is not guaranteed by simply using compliant components. The reasons are varied. Compliance tests on an ...

The input stage of an off-line power converter usually contains an LC averaging filter. A common practice is to damp the LC filter using additional reactive/dissipative components. In this article, we ...

A research team led by Prof. MENG Guowen and Prof. HAN Fangming from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), along with Prof. WEI Bingqing from the University ...

In my May blog post, I described the construction of a low-pass filter that used op-amps, capacitors, and resistors. I ignored thermal drift, long-term accuracy, and other characteristics and tested ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other variable frequency drives (VFD) ...
