I've never tried this, but I've heard (probably here on the EVDL) of using a PWM DC motor controller for this purpose. You'd probably need an inductor in series with its output to simulate motor inductance, so the controller's current limiting circuit would have time to do its job.
A PWM motor controller works fine as a step-down DC/DC "transformer", but you definitely do need to add an output inductor or you'll get pulsating DC. The pulsating DC is fine for a light bulb or motor, but not for battery charging or any kind of load that expects "DC".
