Hello,
situation
currently i'm doing an internship assignment. right now the company has a motor controller with a TRIAC (on/off and phase cutting to control) and a LED dimmer.
The problem of the TRIAC is that it gets very hot, so they need a cooling plate, which cost a lot money when the need to produce a controller.
Assignment
i need to design 1 circuit (universal) without cooling plate for:
1) control for a single phase motor with capacitor (6A/230Vac and 12A/230Vac)
2) LED dimmer (LEDs are also 230Vac)
Problem
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 where i dont need a cooling plate or design a circuit without a rectifier.
it needs to be a design where i dont need a cooling plate, because this is expensive for production.
information
supply voltage is from mains (230Vac 50/60Hz)
