In early 2018, I was bit by the DRSSTC bug when it became apparent just how much heavy iron I had accumulated in my quest to bring my 15kVA Pole Pig powered SGTC online.
I already had a large heatsink salvaged from a 7kVA UPS system. I figured I could reconfigure my existing CDE 942C MMC to get one good for 10kVDC @208A RMS. I simply needed a driver, bus caps, interrupter, IGBTs, and a few other odds and ends to construct the bridge.
This coil is based around a full bridge of CM300HA-24H modules, a 2x2 bus capacitor / doubler arrangement for 6000uF @900VDC, Gao Guangyan’s UD 2.7 driver, and the same 8” secondary and 3⁄8” primary from the 8” SGTC”.
The driver is Loneocean’s UD 2.7C, with the HFBR series ST fiber module installed.
