Abstract :
A new power supply using IGBT is developed in order to investigate the feasibility of use of IGBT to large-scale power supplies for synchrotron magnets. The power supply is constructed with a converter and a chopper block, which are made up of IGBT modules. The active peak power and the maximum output current are 1 MW and 3000 A. The preliminary tests showed the current ripple is a few ×10-6 with only a very small-size passive filter. The paper describes the design parameters of the power supply and the test results in detail
