  • An Analysis of Current-Source Inverters Using High-Frequency WBG Switches
    For several decades, MOS-gated power devices have been the prevalent choice for voltage-source inverters (VSIs) and current-source inverters (CSIs) in machine drives. However, recent advancements in power semiconductor technology, specifically the development of wide bandgap (WBG) power
  • Compact Filtering for High Current & High Frequency Applications (.pdf)
    In today's world of increasing electrical noise, higher speed logic, and more sensitive circuits the need for high frequency noise filtering is especially critical. Noise can enter a circuit through external connections such as the input power source or other transmission lines within the circuit
