hello,

i need to design 1 circuit (universal) for:
1) control for a single phase motor with capacitor (6A 230Vac and 12A/230Vac)
2) LED dimmer (LEDs are also 230Vac)

This will be done with MOSFETs, so i gonna need a rectifier.
The problem is that when i want to attach that motor, i definitely know that there will be high current flowing through the rectifier which will result in heat. is there any option to either design a bridge with minimal heat dissipation or design a circuit without a rectifier?

daniel

EDIT: my supply is from mains (230Vac 50/60Hz, 3 phase) and i want to build a circuit without a cooling profile if that is possible. (i have a reason for this haha)

 

Hi Daniel,
You have already got a Threading running for this project.
