I am looking for an experienced freelancer to develop a Simulink model of a 500W bi-directional isolated AC/DC converter. The input voltage range will be 100-240V from the AC side coupled with a 48V DC side from a LiFePo4 battery. No constructed PCB board is required for the simulating circuit. Additionally, the desired output power of the AC/DC converter should be 500W - 600W. The power convertor needs to be isolated using high frequency transformer (small sized) and should be able to provide AC power when Grid fails and charge battery when Grid is avaiable. Battery is expected to be around 500Wh @48V. If you believe you have the necessary skills to complete this project, I would love to hear from you. Thank you!
