The IGBTs were turning on and off within 20 ns of each other. I thought I took pictures of the scope, but they’re not on the blog.
jyanof, it's actually the HASS500 that was put in place of the HASS300. Max current is 500/300 x 500A = 833A without changing the code. I currently have it set at 625 amps.
