The invention provides a hybrid power electric shunting locomotive converter which comprises two main and auxiliary charging circuits which are redundant to each other, and each main and auxiliary charging circuit comprises a plurality of pre-charging loops, two rectification bidirectional chopping modules, an intermediate DC loop, an inversion bidirectional chopping module and an inversion single-phase chopping module. And an isolation filtering module. Wherein a first port of each rectification bidirectional chopping module is externally connected with a traction transformer through a pre-charging loop, a second port is connected with an intermediate DC loop, and a third port is externally connected with a power battery pack through another pre-charging loop; a first port of the inversion bidirectional chopping module is connected with the intermediate DC loop, and a second port is externally connected with a motor; a first port of the inversion single-phase chopping module is connected with the intermediate DC loop, and a second port is connected with an external AC load or a locomotive garage power supply through the isolation filtering module. The converter is high in redundancy and reliability and comprehensive in function.

    本发明提供了一种混合动力电力调车机车变流器,其包括互为冗余的两个主辅充电路,每个主辅充电路包括多个预充电回路、两个整流双向斩波模块、一个中间直流回路、一个逆变双向斩波模块和一个逆变单相斩波模块,以及一个隔离滤波模块;其中每个整流双向斩波模块的第一端口通过一个预充电回路外接牵引变压器,第二端口连接中间直流回路,第三端口通过另一个预充电回路外接一个动力电池组;逆变双向斩波模块的第一端口连接中间直流回路,第二端口外接电动机;逆变单相斩波模块的第一端口连接中间直流回路,第二端口连接通过隔离滤波模块外接交流负载或机车车库电源。该变流器的冗余性和可靠性较高,并且功能全面。
