Inverting Buck Boost 15v DC to -15v DC

This circuit is self designed and converts positive DC to coresponding negative DC.  It is one rail,   Blue is Load Current.   It is a good Design, think because the controlling circuit are four op amps only and you dont need special Chip.   Also It can work with Power Mosfets for very high Current needs.  3 amps Mosfets deliver 1 amp output Current easly.

looks messy and could work with just one OpAmp but it works even with a lot of regulator ripple up and down. Load down to 20 Ohm for max stress but as always CFS stops the fun, thats an issue of Everycircuit dont worry.

ahh, the headline "buck boost" is unclear looks more like a zeta boost. buck and boost is not explained how this mode does change.

Thanx for comment. Spent 2 days doing this. Op amps control the output voltage. It can Step up and down too. Opamp circuitry is Inverter, comparator and latch.

Ripple goes away by adding another LC. Will make It better 😉
