Jez Smith said:
A MOSFET driver and to control the motor speed you use Pulse Width Modulation. Sure, that's all, and the experience to turn on Mosfets fast enough to not fry them, and protection to stop you buggering the devices when you accidentally short the bridge out in development , and , and and. The topology is relatively straightforward, but you need some practice first to do it with welding currents ! Its the rest that takes experience we cannot readily offer. This is not a power forum when all is said and done. Steve |

| High current Dc motor controller | 01/01/70 00:00 | |
| More detail required | 01/01/70 00:00 | |
| try these ics | 01/01/70 00:00 | |
| for drivers, there is, in my opinion, ONE source | 01/01/70 00:00 | |
| I would use a MOSFET instead of relay | 01/01/70 00:00 | |
| more details | 01/01/70 00:00 | |
| Well i think that Relay is Best Solution for you, | 01/01/70 00:00 | |
| Not suitable - no speed control! | 01/01/70 00:00 | |
| 800 A ??? | 01/01/70 00:00 | |
| Are you sure? | 01/01/70 00:00 | |
| High is relative | 01/01/70 00:00 | |
| you need a H-bridge as has been mentioned | 01/01/70 00:00 | |
| Topology is simple | 01/01/70 00:00 | |
| Tutorial | 01/01/70 00:00 | |
| good info | 01/01/70 00:00 | |
| The +1 karma point came from me,... | 01/01/70 00:00 | |
| relay will work ,but | 01/01/70 00:00 | |
| better power amp | 01/01/70 00:00 | |
