Hi, I guess to know, can I use voltage 5v from resistor divider 1:5 to get it from unstable 27v DC supply (+-10%) for Arduino power on and simultaneously use this voltage to create 2 stable voltages +5V and +27v (+-1%) and AC voltage 60v?

I guess to create it by using PWM pins and isolated transformer and power transistor for output,
but I'm worry about how to get voltage more, than 27 V with PWM positive pulse only?

May be I need some additoinal block to create PWM 27V to 30v and 60v? But ever don't image, which kind of sch.diagram or decision can I use to.


I guess to  make this project with educational purposes only to check Arduino possibilities in power supply creation, so, will be appreciated decision or sch.diagrams where used Arduino only and passive elements.

Thanks.

Absolutely not. Use a DC-DC converter instead, like this one.

It takes considerable skill in electronics to make a useful DC-AC inverter.
