Power quality describes the quality of voltage and current a facility has,
and is one of the most important considerations in industrial and
commercial applications today. It is essential that processes, in
particular, in industrial plants, operate uninterrupted where high
productivity levels are an important factor.
The Automatic Voltage Regulator (AVR) is widely used in electrical power
field to obtain the stability and good regulation of the electric system.
In this paper, a novel ac automatic voltage regulator (AVR) is proposed.
This AVR is configured by an input inductor, an output filter, a small-
capacitance dc capacitor. This power converter acts as an ac boost
converter when the utility voltage is lower than the specified voltage. On
the contrary, this power converter acts as an ac buck converter when the
utility voltage is higher than the specified voltage. Hence, the output
voltage of the AVR can be maintained at the specified voltage. The salient
feature of this AVR is that the power electronic switches are switched in
high frequency therefore the switching loss of this AVR can be reduced and
the capacitance of the dc capacitor is very small. Hence, the size and
cost can be reduced, while the reliability and power efficiency can be
increased. A prototype is developed and tested to verify the performance
of the proposed AVR.

自动电压调节器（AVR）是广泛应用于电力领域获得稳定和电气系统良好的调节。在本文中，一种新
型的交流自动电压调节器（AVR）提出。这是一个 AVR 输入电感配置输出滤波器，一个小电容直流电
容器。该功率变换器作为交流升压转换器，当电网电压低于规定电压。相反，该功率变换器作为交流
降压转换器，当电网电压高于额定电压。因此，对 AVR 的输出电压可以保持在指定的电压。这个 AVR
的显著特征是，电力电子开关切换频率高，因此本 AVR 可以降低开关损耗和直流电容器的电容很小。
因此，尺寸和成本可以降低，而可靠性和功率效率可以提高。原型开发和测试，验证了 AVR 单片机的
性能。
