A flexible DC link-global soft switch-full bridge inverter for MH(Metal Kailed) lamps has been proposed.The main contributions of the paper are as follows:(1) A new topology about DC link
using Buck converter as DC link
has been given out;(2) A ZCS-ZVS-PWM-Buck converter has been analyzed;(3) A new controlling strategy for the inverter has been developed.The results of the simulation and experiments (with output power of 2.7kW) provided in the paper have shown that the new inverter has many merits.
