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 ...
The constancy of output voltage in a DC/DC output network is critical to SMPS (switched-mode power supply) electronic performance. When different output voltages are required by the circuit ...
Pulse-skipping mode (PSM) is widely used as a method for improving the efficiency at light load. For this example, we will use the TPS65290 which has adopted PSM. A simplified block diagram and an ...
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 ...
Cornell Dubilier has released a range of long-life film capacitors optimised for ac harmonic filtering on the input and output of inverters. Called the ALH series and with a 1,500 hour rating (see ...
A research team led by Prof. MENG Guowen and Prof. HAN Fangming from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), along with Prof. WEI Bingqing from the ...
Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...
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 ...
Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
