Proved by the theoretic deriving and simulation result, the COFDM modulation technology is well suitable for highvoltage PLC with a high transmission speed, low BER and high reliability.
The concerted control strategy of rectifier and inverter is analyzed to keep highmodulation degree of SPWM, which achieves quick response and high resolution of excitation voltage regulation.
