Hi All,
Just curious, but what are the main differences between using mosFETs and an H-bridge design, versus power op-amps for motor control or for peltier control?
I've only seen H-bridge designs before but I stumbled across the idea of using power op-amps which can be used to output a linear voltage.
With an H-bridge design, for a peltier cooler, I would pwm the FETs and then filter out the signal to get a nice, smooth voltage. It seems that using a DAC and power op-amps would also be another way of doing this.
What are the advantages/disadvantages of each?
Thanks!
