Abstract
The present invention relates to a basic function unit of voltage source converter, which is characterized in that the basic function unit includes a switching device function module, a by-pass function module, a switch protection function module, a secondary control and protection function module, and a energy storage unit. The secondary control and protection function module, the energy storage unit and the by-pass function module are all fixed on the motherboard, there is a slide rail at the bottom of the motherboard, the motherboard can move back and forth on the slide rail. The voltage source converter based on that unit is highly modular, insensitive to switch device parameters, lower output voltage change rate, and smaller dv/dt stress of equipment, smaller noise, without filter, convenient installation and maintenance.
