查询词典 zero access

This invention relates to a cascade multiple zero-type matrix rectifier, in which, a general input filter is connected between a net and a step-down transformer to get sine-wave input current, the step-down transformer includes n secondary windings with Yn spliced mid lines, the phase of all the three-phase windings is the same, the rectifier array is arrayed in a 1 row x n lines by n zero-matrix rectifier units, each line of which is connected with the seconday winding of the step-down transfornmer, and the outputs of the rectifier units are serial orderly to form a DC output, the general controller is responsible for regulating work of the entire system and connected with the branch controllers by signal cables to control the work of the rectifier units in the array.

本发明涉及一种级联多重化零式矩阵整流器，总输入滤波器连接在电网与降压变压器之间，滤波得到正弦波形的输入电流，降压变压器有n个Yn接带中性线的次级绕组，所有三相绕组相位相同，整流器阵列由n个零式矩阵整流器单元排成1列×n行的阵列，阵列中每一行与降压变压器的一个次级绕组对应连接，阵列中整流器单元的输出依次串联，形成一路直流输出，总控制器负责控制调节整个系统的工作，并通过信号电缆与各个分控制器联络，控制整流器阵列中每个整流器单元的工作。本发明由低压小功率的变换器串联得到幅值可调的高压直流电源，同时在电网侧得到位移为零的输入电流，具有网侧四象限运行能力等优点，适用于中高压直流供电领域。

The proposed inverter has a new auxiliary resonant commutation cell. It provides that all main switching power devices in the soft-switching inverter operate at zero-voltage-switching turned-on and the auxiliary switches operate at zero-current-switching turned-off. In addition, this thesis presents an improved control scheme to minimize the operation of auxiliary resonant circuit for efficiency improvement.
