Radium needles that were once implanted into tumours as a cancer treatment are now obsolete and constitute a radioactive waste problem, as their half-life is 1600 years. We are investigating the reduction of radium by transmutation on a small scale by bombarding Ra-226 with high-energy photons from a medical linear accelerator (linac) to produce Ra-225, which subsequently decays to Ac-225, whic...

The article presents an induction generator connected to the power grid using AC/DC/AC converter and LCL coupling filter. Three-level inverters were used in converter, both from side side. algorithm realizing Pulse Width Modulation (PWM) has been simplified maximum. Control of was based on Direct Field-Oriented (DFOC) method. At same time, voltage control for this solution. MPPT extended includ...

The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were pr...

This paper presents a new method to compensate the nonlinearity for matrix converter drives using disturbance observer. The nonlinearity of matrix converter drives such as commutation delay, turn-on and turn-off time of switching device, and on-state switching device voltage drop is modeled by disturbance observer and compensated. The proposed method does not need any additional hardware and of...

This paper is focused on a design of high-voltage (HV) generator, which proposed for high-frequency irreversible electroporation (H-FIRE). The generator produces bursts bipolar symmetrical pulses. Most HV sources used cell are based controlled discharge capacitor into resistive load. solution very simple, but it associated with certain risk an uncontrolled the capacitor. We present different ty...

The topology and management of a sustainable dual-bus, AC DC, microgrid designed to operate connected weak grid is presented. AC+DC hybrid microgrids are robust cost-competitive solution for poorly areas, as can be found in rural or island electrification. versatile proposed this work developed around wind turbine based on particular induction generator with double stator winding squirrel cage ...
