Research of High Speed Circuits Signal Integrity of Controller Platform in Power System

Signal integrity(SI) of high speed circuits of the control platform for IGBT series valve is analyzed. The PCB impedance calculation is performed to analyze the effects of through hole radius, wiring length and width on signal integrity. The optimized parameters are found after calculation. The experimental results show that it is beneficial to improve the signal quality by optimizing routing parameters. Potential system failure for high speed signal overshoot and ringing phenomenon is also avoided.
