KEY CONSIDERATION IN BUS BAR DESIGN

FOR WIND POWER CONVERTER

Differentiated from normal inverter and normal converter, wind power converter operates always under critically bad working conditions which include high power density, harsh working environment, long full-load operation time, and large power fluctuation. 

Major consideration of bus bar design includes but not limit stray inductance mitigation, stress carrying capacity, and necessary Ingress Protection Rating against dust and humidity. The wind power industry faces challenges of high power generation cost, tough working conditions. These challenges require laminated bus bars to have very high reliability to meet various wind environments.

Benefit from our vast knowledge and experience on laminated bus bar designs for different wind environments, NORTHBRIDGES has solved the technical challenges and delivered various solutions to meet the specific power generation applications ranging from off-shore, high altitude land, to low wind speed wind conditions.

A example of NORTHBRIDGES's multiple solutions for an high power off-shore wind converter.

The Capacitor bus bar used Edge-sealed design to ensure the Creepage Distance and Minimum Clearance, while greatly reduced bus bar inductance. The IGBT bus bar used epoxy-powder painted design, which enhanced the electrical performance, especially increased puncture voltage resistance.
