| 摘 要： | 简要介绍了三相四线制并联有源滤波器在电流滞环控制下的工作方式,详细分析了非理想条件下电路延时对电流滞环控制的影响,并以三相不控整流负载为例推导了在电路延时作用下的开关频率,在一台50 kVA三相四线有源滤波器装置上进行了开关频率上下限的实验验证,证明了公式的准确性.

| Abstract: | This paper briefly introduces the circuit work mode using current hysteresis control in three-phase four-wire parallel active power filter,analyzes the influence of circuit delay on the current hysteresis control in non-ideal condition in detail and derives a theory formula of the switch frequency in the non-ideal condition using three phase diode rectifier as the harmonic source.A test on 50kVA implementation has been carried out for verifying the maximum and minimum switch frequency to validate the correctness of the derived formulas. |
