Phase-Control of a Rising Sun Magnetron Using a Modulated, Addressable, Current Source

Dynamic Phase-Control of a Rising Sun Magnetron Using Modulated and Continuous Current

Phase-control of a magnetron is studied via simulation using a combination of a continuous current source and a modulated current source. The addressable, modulated current source is turned ON and OFF at the magnetron operating frequency in order to control the electron injection and the spoke phase. Prior simulation work using a 2D model of a Rising Sun magnetron showed that the use of 100% mo...

The Vector Control of Three-Phase Salient Pole Synchronous Machines Supplied by Pulse-Width- Modulated Voltage Source Inverters

In this paper, computer simulation of a three-phase synchronous motor drive is described. This drive/system is supplied with a new type of pulse-width modulated voltage source inverter (PWM VSI) whose amplitude of the first harmonic, compared to a conventional sinusoidal PWM VSI, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...
