具有辅助电压输出的整流器
摘要：
公开了一种具有辅助电压输出的整流器。整流器包括被配置为接收交流输入电压的两个输入路径、被配置为提供直流输出电压的两个输出路径、和被配置为提供辅助输出电压的辅助输出路径。至少两个整流路径被连接在输入和输出路径中的每个之间。至少两个整流路径是被连接到同一输出路径的开关模式整流路径。两个开关模式整流路径被配置为在输入电压的一个半波期间将一个输出路径连接到一个输入路径，并且在另一半波期间将该一个输出路径连接到另一输入路径。两个开关模式整流路径的每个包括具有可控制的路径的两个半导体元件，可控制的路径通过辅助输出节点而与彼此串联连接。至少一个整流器元件被连接在辅助输出和两个辅助输出节点之间。
摘要（英）：

A rectifier includes two input paths configured to receive an alternating input voltage, two output paths configured to provide a direct output voltage, and an auxiliary output path configured to provide an auxiliary output voltage. At least two rectifying paths are connected between each of the input and output paths. At least two rectifying paths are switched-mode rectifying paths that are connected to the same output path. The two switched-mode rectifying paths are configured to connect one output path to one input path during one half wave of the input voltage, and to connect the one output path to the other input path during the other half wave. The two switched-mode rectifying paths each comprise two semiconductor elements with controllable paths that are series-connected with each other by an auxiliary output node. At least one rectifier element is connected between the auxiliary output and the two auxiliary output nodes.
