Posted on September 28, 2014 at 19:15Hi everyone,
I have to develop a PMDC motor control. The main requirement is the
maximum possible efficiency
. Since I'm interested in a one way rotational direction, I thought that a low-side control (chopper) could be a good choice. Am I right?
System specification:
- 200W PMDC motor;
-10A maximum current;
-30V supply voltage.
Even if I know how to lay down a basic design of a low-side control, I have no experience about choosing components. So, my question is: which MOS, MOS driver and freewheeling diode should I choose to achieve the highest possible efficiency?
Are there any other tricks for the efficiency sake?
Thanks in advance
