The solid state motor drive includes bank selection cir- cuits, which select the operative converter bank at any instant, and firing circuits for providing firing pulses for the selected converter bank. The energization and deenergization of the bank selection circuits and firing circuits are controlled such that the bank selection circuits are energized before the firing circuits, and, upon loss of power, the bank selection circuits are deenergized after the firing circuits.
