A 10 MW-class high-precision power supply was developed for the electromagnets of a large proton accelerator (J-PARC). This power supply consists of an advanced self-commutated current-source type converter (ACSC) using IEGTs and a hybrid filter. The current ripple was less than 1×10 -6 , and the tracking error was less than ±0.5×10 -4 . With this power supply, the proton beam was successfully accelerated to 30 GeV, which is the target energy of the first stage of J-PARC.
