Is it feasible to manufacture a negative gate SCR?
What would be the problems/disadvantages of developing a negative gate SCR for production or for OEM?
A negative gate SCR would have its advatage/s in use with an H-Bridge. No need for a high-side driver.
A negative gate SCR on the high side would allow what a positive gate SCR does on the low side, i.e., a simple pulse to gate the SCR.
