Driving high inductance Solenoid using H-Bridge

koniho said:

I'm currently free-wheeling by keeping the low-side of the bridge on after the solenoid is energized. Would it be better to free-wheel on the high-side? Are there any advantages/disadvantages in this application?

I've never really been clear on this decision.

Hello again,

The idea here is that since the conduction of any transistor causes power dissipation then the best way to handle it is to try to distribute the power between all the transistors so that no transistor gets hotter than another. To get this to happen you would use the uppers 50 percent of the time and the lowers the other 50 percent of the time which is quite simple.
