System efficiency is an important consideration when inverters are used in photovoltaic, UPS, and motor drive applications. One approach to achieving improved efficiency is to replace the usually-used ...

When we speak of efficiency, we are referring mainly to electrical efficiency. This usage, however, is a restriction of the meaning of the word efficiency itself. In power-electronics applications the ...

Semikron has added a new topology for use in three-level inverters to its Semitop IGBT product range. The topology integrates IGBT technology with lower switching and conduction losses to produce ...

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...

More undocumented applications for the 555 ‘oscillator:’ Not all applications oscillate as we will see. Most are knowledgeable about common CMOS logic inverters and Schmitt triggers such as the 74HC04 ...
