7 / 10 page Voltage Loop-Current Controlled system, and in every pulse there is a regulated power transfer to the load. The resonant LC topology has been chosen in or- der to limit the voltage slew-rate across the coil within reasonable values and so, to minimize irra- diation problems. The negative converter is a simple charge trans- fer: it is supplied by the positive high voltage and it capacitively translates this positive voltage down to a negative one, obviously to limit irradia- tion problems also the charge output has a limited slew-rate; moreover to reduce intermodulation phoenomenas the charge output is synchronized with the LC oscillations of the resonant boost. This negative voltage is (not counting drops on external rectification diodes) in tracking with the positive one and so the negative output controller is not required. - + L L V512 D98IN971A BACK-UP OSCILL.
