3 Terms and definitions

GB/T 1094.6, GB/T 1094.11, GB/T 25092-2010 and GB/T 37011 as defined in the following terms and definitions Applicable to this document. 3.1 Bridge arm reactor armreactor A reactor connected in series on the bridge of the voltage source converter. Note 1. The current flowing under normal conditions consists of DC bias current, power frequency current and superimposed harmonic current, which mainly suppresses the circulation and suppression between the bridge arms. The effect of the bridge arm fault current rising too fast during a short circuit. Note 2. In actual engineering projects, the bridge arm reactor may be arranged on the AC side of the inverter or on the DC side of the inverter. 3.2 Rated inductance ratedinductance Lr ......
