Inovativní postupy při diagnostice částečných výbojů při AC a DC napětí

Partial discharges are one of the most commonly occurring physical phenomena that can have a negative effect on the overall life of electrical equipment. The most basic types (besides surface and internal) are discharges occurring in places with a small radius of curvature. At ...

Pulse width modulation of three phase inverters based on linear programming

Traditional three-phase voltage-source inverters supplied by constant dc-link voltage usually utilize the space vector PWM to achieve maximum output voltage. This paper deals with optimization of inverter leg voltages using linear programming method. System definition is based on the relationship ...
