This paper points to the advantages of using multiple modules of the current-source, sinusoidal pulse-width modulation (SPWM), three-phase six-valve converters as the power conditioner for the superconducting magnetic energy system. A high degree of controllability is obtained by using dynamic SPWM trilogic as the operating strategy. Very low switching losses is assured by using two carrier triangles per modulating cycle. By parallel connection of converter modules, and by phase-shifting the triangle carriers, the following are the gains: (1) increasing the current capacity to the level required by the superconducting magnetic, (2) reduction of conduction losses, (3) meeting harmonic standards, without the need of expensive filter, by harmonic cancellation, and (4) achieving a high-frequency bandwidth.
