How to do highside and lowside switching together in the same circuit. This technique evolves to how switching control is done for H-Bridge circuits.

Very nice well explained video....hey i need about 140 volts transformerless about 60 amps.any suggestions? Thanks

I'm assuming you're asking about a direct current (DC) application and not a new concept (say alternating; AC). It would be difficult to find a single MOSFET with a safe operating range (SOA) like that. I would need to know what you're doing. That's about an 8.4 kW application. I haven't designed anything like that before.

@@pauljstar hello thanks for replying. Scratch those numbers im looking for 40 amp 90 volt dc charger with current variable.its for a e bike if you design and put it on ebay ill gladdy purchase it thanks.

Are you aware of a MOSFET design that could work if there was a load on the high side or low side? Like one circuit that can handle both load configurations

I would just use a high side MOSFET for one application and a low side MOSFET for the other application. It's unusual to move the load's highside or lowside position dynamically in the application (there isn't a lot of reason to do so). Switching between highside power directions is the basis of H-bridges for clockwise and counterclockwise applications.
