The primary phase current and line to line current in the rotor's rectifier were calculated based on the mathematic model in three phase coordinate system. 首先从三相坐标系下的数学模型出发对转子侧整流变压器原边相电流及线电流进行计算分析,并给出相应的傅立叶分析结果。
Primary inverter rectifier outputes positive polarity end and negative polarity end. In bipolar output end, voltage ′ s and current ′ s static characteristic are completely identical with associated dynamic characteristic respectively. 一次逆变整流输出正极性端和负极性端,双极性输出端的电压电流静态特性与动态特性完全相同;
Due to the halved transformer primary voltage, the rectifier diode voltage stresses are reduced distinctly. 由于半桥的特殊结构能够将变压器原边电压减半,输出整流二极管上承受的最大电压也将因此大大减小,从而优化了输出整流器件的设计和选择,同时也为减小变流器的传导损耗创造了条件。
The isolation stage uses a high-frequency transformer to achieve voltage regulation, electric isolation and power transmission, uses a single phase full bridge invert circuit in the primary side and uncontrolled rectifier circuit in the second side. 隔离环节选用高频变压器,其一次侧为单相全桥逆变电路,二次侧为不控整流电路。
