850KW wind cooling wind turbine converter

850KW wind cooling wind turbine converter consists of body-side module and Line-side module. The body-side module uses diode to construct 3-phases diode rectifier, while the line-side module uses 1GB to construct 3-Phase complementary rectifier. Line-side cable is lightning protected by installing lightening guard, provides the customers with 400V/12KVA power supply. The turbine is powered by duty-cycle controllable field power supply with an amplitude value of 150V. The software control policy uses the method of body-side power control and line-side current control, to meet the requirement of line-side harmonic current and excitation current ripple.
