“…The three transformers have similar DC winding resistance where they are constant for frequencies <10 kHz. The measured DC winding resistance is 1.1 Ω validating the estimated value using (9). As expected the winding resistance increases with frequency and the different configurations display varying effects for frequencies above 100 kHz.…”

Three potential options to implement multicore planar transformers using a printed circuit board as windings are presented. The first option utilises a distributed transformer configuration where smaller transformer elements with separate cores are interconnected to function as a single transformer. The second option has a lumped core configuration which uses multiple cores arranged to function as a monolithic core while the third is a hybrid of the first two configurations. The three transformers were designed for a 400/40 V, 1 kW, DC-DC converter application at a switching frequency of 100 kHz. The electrical and thermal characteristics of the three configurations are compared using finite-element analysis of the electromagnetic fields. The simulation results are also validated by measuring the electrical characteristics of transformers fabricated in the three configurations. The electrical and thermal characteristics of the transformers are also verified in a power converter system. Results of the comparison show that the distributed core configuration gave the best thermal characteristic while the lumped core configuration has the least winding losses.

“…Windings are connected in series for high-voltage requirements while for high current applications, windings are connected in parallel [7,8]. Another option, which has been utilised for highfrequency applications is the use of stacked cores lumped as a monolithic core similar to the transformers presented in [9][10][11].…”

“…The efficiency of these systems becomes more and more important as an increasing number of accelerator facilities try to reduce the greenhouse gas emissions [1][2][3]. Pulse modulators, which are based on solidstate switches, have been proven to be able to efficiently generate pulses at high power levels [4], [5]. Typically, IGBT modules are used as solid-state switches as they offer high blocking voltages and current ratings, and these have demonstrated a reliable operation in pulsed power applications [6].…”
