The diode bridge rectifier is a simple circuit used to convert alternating current (AC) into direct current (DC). In this guide, you’ll learn how it works, what it’s used for, and how you can build your own. Even though you may not notice it, the diode bridge rectifier is everywhe...
In this variable-gain voltage amplifier circuit, one op-amp from an LM324N quad opamp package is connected. The gain can range from zero to roughly one hundred. The output of the amplifier is coupled with a DC rectifier circuit composed of D1, D2, C2, and C3. One of the six buffer...
Bridge Rectifier The bridge rectifier is the most commonly used circuit for DC power supplies. It consists of four diodes D1 through D4, as shown in the diagram,connected to form a bridge. During the positive input half cycle, terminal A will be positive and terminal B will be negative. ...
摘要传统双有源桥单级AC-DC变换器的移相调制难以实现全范围软开关,开关管损耗大,效率难以进一步提高。针对此问题,该文提出一种基于临界电流模式(BCM)的调制策略,将移相和调频相结合,实现所有开关管的零电压开通,从而有效地降低了开通损耗。该文分析单级式双向AC-DC变换器的临界电流调制基本原理和软开关实现条件,并...

摘要三相隔离型AC-DC-DC电源因其具有功率密度大、电气隔离等优点,在工业上应用广泛。但在一些负荷频繁投切的特殊应用场景下,如电泳、电镀等,基于传统PI控制的电源存在输出电压响应速度慢及纹波大的问题。为了提升电源的输出电压响应速度,该文在分析线性自抗扰控制中关键带宽参数与输出量之间关系的基础上,提出一种控制...
rectifier. The controlled rectifier is obtained by replacing the diodes of the uncontrolled rectifier with thyristors. Control over the output dc voltage is obtained by controlling the conduction interval of each thyristor. This method is known as phase control and converters are also called “phase ...
5.3. Control Strategy for MMC in Rectifier Side under Unbalanced Grid Voltage The control strategy of three-phase converter based on the αβ coordinate system is shown in Figure 16 [14]. A stable DC-link voltage is required in order for the converter to work properly. This can be achieved...
