The Pegasus Toroidal Experiment at the University of Wisconsin will upgrade their solid-state switching power systems for Local Helicity Injection (LHI) and for magnet driving/control. A new modular system that addresses the output ripple, efficient capacitor bank utilization, and electromagnetic interference is required. Eagle Harbor Technologies (EHT), Inc. is developing a Ćuk converter for fusion science applications. The Ćuk converter has low output ripple; high efficiency; voltage gain greater than one, allowing for deeper energy storage utilization; continuous power flow that lowers output EMI reducing noise generation; continuous input and output current – energy flow from the series capacitor allows for greater control of the injector currents; series arrangements can be utilized that isolates individual switch modules so a failure does not potentially damage all solid-state switches. EHT will utilize previously developed precision gate drive technology that allows for high frequency switching, which reduces the capacitor and inductor values significantly, making the design more compact and lower cost. We will present the Phase I project plan and overview of progress to date.
