N2 - Rotating rectifier plays an important role in Brushless Wound-Rotor Synchronous Starter/Generator (BWRSSG), choosing a suitable rectifier is very essential. In most cases, the out-put current of Full-Bridge Rectifier is higher than Half-Wave Rectifier. However, when facing a longer commutation time, the performance of Full-Bridge Rectifier will be worse than Half-Wave Rectifier. Unfortunately, due to the parameters of Main Exciter (ME) and working state of the excitation system, the rectifier in the BWRSSG always works in Two Phases/Three Phases Alternating Commutation mode. In this state, the performance of Full-Bridge Rectifier is lower than Half-Wave Rectifier. Based on the steady-state equations of voltage and current, the field current of two different rectifiers are derived. Using these analytic expressions, the steady-state analytic out-put current of two rectifiers are calculated, respectively. It is found that when both work in two phases shorting and three phases shorting mode, the output current of Half-Wave Rectifier is higher than Full-Bridge Rectifier. Simulation results verifies the analysis and the proposed mathematical expressions.
