INDEX TERMS WT-PWM modulation strategy, high-frequency resonance instability, suppression method, train-network power supply system.  ...  Aiming at the high-frequency resonance instability phenomenon in high-speed railways and traction network (simplified as "train-network") system, a new modulation strategy is proposed.  ...  Besides, if there are multiple frequencies resonance in the system, WRHE-PWM strategy cannot suppress harmonics in all resonance frequencies.  ...
