Question

Was integrated electric propulsion delayed mainly by power electronics and frequency regulation?

Short answer

Power electronics and frequency regulation mattered alongside motors, circuit protection, metallurgy and compatible electrical systems.

Notes

Lexington battlecruiser and carrier machinery is treated as an early step towards integrated electric propulsion. It is explicitly distinguished from a completed integrated system. Suitable motors, circuit protection and dependable operation across the ship were needed. Frequency regulation and power electronics mattered alongside metallurgy and understanding how the systems worked together. Voltage, current and frequency all required appropriate choices.
