摘要
为了提高基波抑制装置的性能,本文提出一种新的实用型有源T型桥基波抑制电路,它可以较好地解决基波抑制和谐波保持问题。理论分析和实验表明,电路的基波抑制度可达94dB以上,谐波衰减率不大于5%。在该基波抑制电路中设计了中和电路,消除了分布电容的影响,提高了基波抑制电路的应用范围。
To improve the performance of fundamental suppression device, a new design of efficient fundamental suppression circuit with active power bridge T was proposed, which works successfully for fundamental suppressing and harmonic keeping. Theoretical analysis and experimental results show that the fundamental suppression ratio is more than 94dB and the harmonic attenuation ratio is no more than 5%.The designed neutralization circuit reduces the effect of distributed capacitance and expands the application scope of the fundamental suppression circuit.
