I want to design a variable power supply. I need to get output voltage from 7.5 to 30 V and output current of 0-40 A.
One of the above values will be fixed while the other changes. This is for resistive load (chlorinator cell whose load changes with the salinity of water and temperature). I bought this boost converter from ebay.
- They provide 400 watt power.
- Input voltage DC 8.5-50 V
- Current: 15 A max
- Output Voltage: 10-60 V (nearly meeting my expectation).
- Output Current : 0.2-12 A (I want up to 40 A).
On eBay, they say we can connect them in parall to get higher power but they have mentioned that only for the 1200 W model. Is there any way I can achieve my goal by using these boost models or is there any other ways besides boost model to get these outputs values? I thought about using voltage selector on primary side of the transformer but the problem is the high output current on the load side.
