This mini TC has 15cm long secondary, and producing about 20cm long sparks half bridge consist of two IGBTs - HGTG11N120CND. Preformance is nothing extra but this is not full power cause i have some chokes on mains, in future i wanna run this mini coil with full bridge or put a doubler on bridge as those IGBTs are dimensioned for 1200V.
