A high-frequency linked three-level phase-shift ZVS-PWM DC-DC converter for distributed DC power feeder

This paper presents some experimental results and practical evaluations of a high-frequency linked three-level phase-shift ZVS-PWM half bridge DC-DC high power converter for distributed DC power feeder. This new DC-DC converter with neutral point clamping and flying capacitor hybrid configuration is implemented by modifying the high-frequency-linked HB soft switching PWM DC-DC power converter with high side and low side two active edge resonant cells, which is previously-developed by the authors. The operating principle of the three-level phase-shift ZVS-PWM DC-DC converter and its experimental and simulation results including power regulation characteristics vs. phase-shifted angle and power conversion efficiency characteristics in addition to power loss analysis are illustrated and discussed from a practical point of view, along with the remarkable advantageous features as compared with previously-developed soft switching PWM DC-DC converter with high frequency AC link.
