2. Soft-switching three-level inverter - Wikipedia

   en.wikipedia.org/wiki/Soft-switching_three-level...

   A soft-switching three-level inverter (S3L inverter) is a high-efficiency power electronic inverter intended, in particular, for use with three-phase drives, as a grid-tie inverter for photovoltaic installations or wind turbines and in power supplies. [1] The topology was developed in 2009 at HTWG Konstanz (Constance University of Applied ...

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   3-phase inverter switching circuit showing 6-step switching sequence and waveform of voltage between terminals A and C (2 3 − 2 states) To construct inverters with higher power ratings, two six-step three-phase inverters can be connected in parallel for a higher current rating or in series for a higher voltage rating.

4. Pulse-width modulation - Wikipedia

   en.wikipedia.org/wiki/Pulse-width_modulation

   Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an

5. Electricity sector in Sri Lanka - Wikipedia

   en.wikipedia.org/.../Electricity_sector_in_Sri_Lanka

   The proposed connection involves the linking of the national grids of India and Sri Lanka via Rameshwaram in south India and Talaimannar in north-west Sri Lanka. The project involves the construction of a HVDC connection between Madurai in southern India and Anuradhapura in central Sri Lanka, through the Palk Strait. The link would measure ...

6. Vienna rectifier - Wikipedia

   en.wikipedia.org/wiki/Vienna_rectifier

   Fig. 2: Top and bottom views of an air-cooled 10kW-Vienna Rectifier (400kHz PWM). The Vienna Rectifier is useful wherever six-switch converters are used for achieving sinusoidal mains current and controlled output voltage, when no energy feedback from the load into the mains is available.

   Mariusz Malinowski participated in the development of technologies which received many prizes e.g. three times the recognition in the competition Polish Product of the Future organized by the Polish Agency for Enterprise Development (PARP), the Grand Prix of TECHNICON, the Gold Medal of Automaticon, the Grand Prix Exhibition of Innovations in ...

8. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   The inverter stage converts DC, whether directly from the input or from the rectifier stage described above, to AC by running it through a power oscillator, whose output transformer is very small with few windings, at a frequency of tens or hundreds of kilohertz. The frequency is usually chosen to be above 20 kHz, to make it inaudible to humans.
