What are the consequences of a generator operating at too low a voltage?

If the DC bus voltage is too high, electrical components that are regularly operated with power, such as instruments, relays, indicator lights, etc., are easily damaged by overheating. If the voltage is too low, the protection may malfunction or refuse to operate.

Permanent magnet generator vs excitation generator

High-efficiency permanent magnet generators have a high specific power, high efficiency, high speed, high reliability, less heat generation, lightweight, simple structure, and small size.

What is a permanent magnet generator and its adjustment method?

The permanent magnet generator refers to a power generation device that converts mechanical energy from thermal energy into electrical energy.
