| Abstract |
There are various solutions for reducing turn-off loss of insulated gate bipolar transistor (IGBT). The ‘zero current transition pulse width modulation’ (ZCT-PWM) technique is one of them. For ZCT-PWM technique, the gate signal of auxiliary switch, which is synchronized to the gate signal of main switch is needed. This paper describes the implementation of both gate signals which is comprised of the main switch and the auxiliary switch using a digital signal processor (DSP), and 300-W ZCT-PWM boost converter is designed and implemented to verify ZCT technique. |
