This construction is based on DRSSTC 1 Ward, except the control electronics. Predicter works in the coil as a driver, along with bridge that controls the gates of big transistors IGBT. The bridge is powered by 40V. In controls the pulse transformer GDT with a gear 2:1:1:1:1, what allows greater current efficiency in pulse driver. The main bridge is based on IGBT SKM300GB124D transistors linked in configuration of a full bridge. IGBT are protected by transils connected in parallel 2x200V and snubbers that absorbs the voltage peaks 2x5uF. Electrolyte 10000uF/350V was used to filter the voltage powering the bridge. MMC with a capacity of 450nF/4kV works in the original resonant circuit. Capacitors CDE 942C20P15K-F were used for this purpose. The primary winding was made flat and wound by a copper tube fi 6mm. The whole resonant circuit was connected by a cable 10mm^. The secondary winding was wound with a wire 0,25mm on a tube fi 160mm, 60cm long. Toruses were made of aluminum vent pipe. Secondary circuit resonant frequency is about 70kHz. Current limiter is set at about 700A.
Interrupter was connected with Tesla by the fiber, what increases safety and prevents unwanted microcontroller crash. Tesla is powered by the rectified mains voltage of about 310VDC.
