| Popis: | This paper presents the relevancy, design, and test results of a mobile electrical vehicle for the applications of testing and providing electromagnetic interferences in Wi-Fi signal in the band 2.4–2.5 GHz. The mobile device includes power electronics supplying a magnetron device for the interference. Propulsion of the mobile device is implemented by using a system of stepper motors. The mobile device is controlled with the help of the microcontroller ATmega 16. For the interfering part, it is necessary to design the power electronics to supply the magnetron from the battery. The power electronics interface between a battery and magnetron must be able to transfer output battery voltage 12 VDC to the variable output 4000 VAC and power around 1 kW. The magnetron is used as a source of electromagnetic interference high-frequency acting on targets, which operates in the band of Wi-Fi signal. In addition, the system must be able to control the direction and power of EMI interferences. The investigations of the power-efficiency of power inverter versus power density will be discussed and optimised here. |
