Description: 采样控制理论中有一个重要结论：冲量相等而形状不同的窄脉冲加在具有惯性的环节上时，其效果基本相同。PWM控制技术就是以该结论为理论基础，对半导体开关器件的导通和关断进行控制，使输出端得到一系列幅值相等而宽度不相等的脉冲，用这些脉冲来代替正弦波或其他所需要的波形。
对不了解PWM的开发人员很有帮助。-Sampling control theory have an important conclusion: the same impulse and different shapes of the narrow pulse increases with the inertia of the link, its effect is basically the same. PWM control technique is the theoretical basis for the conclusion of the semiconductor switching device and the on-off control, so that the output has been a series of equal amplitude and pulse width are not equal, use the pulse to replace the sine wave or other by waveform needs. PWM of the developers do not understand very helpful. Platform: |

Description: Flexible alternating-current transmission systems (FACTS) is a recent technological
development in electrical power systems. It builds on the great many advances achieved in
high-current, high-power semiconductor device technology, digital control and signals
conditioning. From the power systems engineering perspective, the wealth of experience
gained with the commissioning and operation of high-voltage direct-current (HVDC) links
and static VAR compensator (SVC) systems, over many decades, in many parts of the globe,
may have provided the driving force for searching deeper into the use of emerging power
electronic equipment and techniques, Platform: |
