| description | The diode threelevel neutralpointclamped (3LNPC) converter with full power is a promising multilevel topology in the application of wind power generation system. In view of the 5MW directdrive wind power generator with permanent magnet, this paper investigated the control system, main loop parameters, stator flux estimation and discontinuous pulsewidth modulation (DPWM) of the fullpower 3LNPC converter. The gridside converter emploied the grid voltage oriented control and space voltage pulse width modulation (SVPWM) strategy, while the rotor field orientated vector control and DPWM strategy were adopted in the rotorside converter. In addition, lowpassfiltercompensationintegrator (LPFCI) based rotor flux position estimation control method is proposed. The result of thermal simulation indicates that when the switching frequency of the gridside converter is 1.55kHz, the junction temperature and temperature rise of IGBT conform with design regulation. Furthermore, the 25kw experimental prototype illustrates that based on the technique and stator flux estimation as mentioned in the paper, the harmonics content is quanlified with international standards，and the system has small rotor position estimation error, excellent steadystate performance and torque dynamic response meeting with systematic control requirements. |
