DC Soft Start
DC Soft Start
(OP)
Hello,
I am looking to implement a "soft start" solution on a DC starting motor and I am running out of ideas. The motor itself is capable of drawing a maximum 2000A @ 70VDC (very short period of time mind you), and therefore I am limited to the components that I can use. I originally thought an IGBT with PWM might work but cannot find much information on controlling the power in a smooth manner (to essentially limit the in rush current).
Any ideas?
Thanks!

In addition, a soft start applied to a load such as a starting motor sees may fail. Soft starts are not noted for high starting torque when applied to induction motors.
