Hi , I am experienced in power electronics and did SMPS designs. I am interested to work together with you and may I know more about your requirements ? 1) Do you have any target price for SMPS? 2) Do you need isolation. For 3000 W I prefer SMPS with Isolation 3) Whether the boost is a variable supply?
