    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!

At 500w, another switch is set to turn on. If this jump in exported power happens quickly, both switches will turn on, but then this is too much load and so now I'm importing power and a switch turns back off. I'd like a delay in the sequence; "turn on switchA" wait to see if there's still excess power, if so, turn on the next switch, etc. Task 3...

    ...washing machine. The same swap of an AC motor for DC would be done, but the circuit would need to no only do the wash agitation, but also control the water pumps that bring water into the machine, and pump water out of the machine. It would also then have to control the spin cycle - a more powerful motor is probably going to be used for this, maybe 500W instead of 250W, because spinning takes more power. We have tested this ourselves and a 500W DC motor works ok. 1500rpm is a pretty typical spinning speed. The control cycle for the full washing program would be something like this: - 5 minutes ON for water-in pump to fill the washing machine, then turn OFF - 15 minute main motor ON for washing cycle with agitation as described above - 5 minutes ON for water-out pump to emp...
