218VDC TO ALTERNATING CURRENT
August 5, 2020 - 12:01pm

Hi there! I am having a circuit from blender motor. I want to change its voltage (218vdc) to Ac voltage, feed them into voltage multplier boosting to 400-435v. This will be for capacitors bank charging. Is the any way simpler I can convert this DC supply?

You need custom inverter circuit that will synchornously boost the 218VDC to a step up tranformer. It is not a simple circuit but a complex one.

Did you calculated maximum current output?

No, I did not measure the current. Maybe I will burn my multimeter. And I hope current are too high because the circuit was for 775motor

Best way to have an AC transformer with step up facility. However, have a decent knowledge about what  is the output frequency you require.

THen simply use a transformer and convert it from available wall output voltage to the required AC voltage. Simple, cost effective and will do the Job.
