I have a transformer with four taps and I use two relays to switch between them:
When both relays are energized, they consume ~60 mA which really is a waste. I want to switch between taps of transformer with something that draws less current.
I was thinking to use four logic-level mosfets but mosfets have an internal diode which will do unwanted half bridge rectification...
What options do I have other than relays and mosfet to switch between taps of transformer?
12 V Relays are on the secondary side of transformer, relays and controller (MCU) are powered from another winding of same transformer which is independent from this four tap winding.
