This thesis Is intended as a medium of instruction, academic performance power electronics. Since the study course Practical Power Electronics Optional equipment used in controlled trials Thyristors. Therefore, it has been thought to create. Trial device detonated Thyristor controlled microcontroller. By bringing out the battery microcontroller to create a trigger. Also published a guide for use in conjunction trial. Air detonated Thyristors up of 10 pieces, which can be designed to meet the purpose of use.
