An equalization design of boost transform for heavy frequency pulsed laser power supply in CRM state

In this paper, the advantages of staggered parallel CRM-Boost circuit topology are analyzed. A balanced two-phase staggered parallel CRM-the Boost circuit control method is programs to solve the shortcoming of the master and slave control method, A 1.6 kW experimental prototype of a two-phase staggered parallel CRM-Boost converter is built by using PSIM software. Input AC 220v, output DC 400v, efficiency 99%, and experimentally debugged. Based on the simulation and experimental waveform analysis, it is proved that the design of the balanced voltage transition of the laser power supply with heavy frequency pulse is reasonable and feasible.
