I need your help to convert 220v 50hz to 115v 400hz. Its for an aviation project. I really need some advices abt how to reach 400hz from 50hz. I searched for frequency converters but couldnt find any circuit schematic. I need build it my own. PLease help me
Hi,
There could be a better solution, but you could try this.
First convert the 220v AC to DC by means of a bridge rectifier. Filter this. Then have a power stage with 4 MOSFETs/IGBTs driven by a control section that produces 2 outputs of 400Hz that drives the MOSFETs/IGBTs using hi-lo side drivers. Adjust the duty cycle as required to get 115v and then filter the output.

Thx for ur advice.But pls let me ask few questions. I understood the way till changing frequency. What u mean exactly with "a power stage with 4 MOSFETs/IGBTs driven by a control section". My education is mostly orriented with aviation so I have less knowladge about electrnoic. Could you please help me ? How can i find the prober schematic to my project ?
