本文在分析晶阐管系统的低功率因数,电网电压波形畸变,高谐波等所造成的公害基础上,提出迅速发展巨型晶体管系统。它可控性好,工作频率高响应快,可以用高频斩波的方法设计直流、交流电机等系统以及逆变、变频系统。最后使系统简单可靠,提高功率因数,没有由于换流压降而产生的电网电压波形畸变,用较小的滤波装置即可减少谐波的危害。
Based on the analysis of the pollution caused by the low power factor, distortion of the grid voltage waveform and high harmonics of the crystal tube system, this paper proposes the rapid development of a giant transistor system. Its controllability, high frequency response fast, high-frequency chopper method can be used to design DC, AC motors and other systems and inverter, frequency conversion system. Finally, the system is simple and reliable, improve the power factor, there is no grid voltage waveform distortion due to the commutation voltage drop, with a smaller filter device can reduce the harm of harmonics.
