摘要：
The reason why the neutral point voltage fluctuates is analyzed in detail and a current-sensorless hysteresis control strategy proposed. This way to balance the neutral-point voltage is simple and not need of current sensor. Based on small signal control model and neutral-point voltage balanced technique the experimental prototype are given and the experimental results verify that the proposed mathematic is correct and the balance of neutral-point voltage guarantee high power factor of TL-PWM rectifier.
