Based on the Fokker_Planck equation,we analytically studied the mechanism of ultrashort pulse laser ablating fused silica,and establish the mathematical model of the fused silica ablation mechanism resulting from the avalanche ionization and multiphoton ionization.

Dynamic simulation of voltage collapse in power systems with NETOMAC;

An effective control of electric power system voltage collapse;

On-load tap changer(OLTC) is considered to be one of the important factors that results in voltage collapse.

This driver uses a transistor which has a low avalanche voltage to sharp the trigger pulse,and then use the pulse which is obtained from this transistor to trigger the Marx bank circuit.
