We digitally implement an extremum seeking (ES) algorithm, which optimizes the rise time of the output voltage of a high voltage converter modulator (HVCM) at the Los Alamos Neutron Science Center by iteratively, simultaneously tuning the first eight switching edges of each of the three-phase drive waveforms (24 variables total). We achieve a 50 rise time, which is reduction in half, compared...
Power modulators for high energy physics accelerators and similar systems are required to generate a series of high quality voltage pulses to power an Radio Frequency (RF) tube. Each pulse lasts several milliseconds in time, and needs to be perfectly regulated in magnitude. A stringent pulse dynamics (that with a fast rise time but no overshoot) is also demanded to ensure high conversion efficiency...
High Voltage Converter Modulators (HVCM) offer significant performance advantages over conventional modulator technologies for long pulse applications. One of the key advantages of HVCM technology is the ability to compensate for capacitor bank droop. Achieving droop compensation without incurring significant additional switching loss has not been possible in existing designs. This paper presents...
