N2 - This paper presents high voltage generator for stun gun applications. The proposed high voltage generator consists of coupled-inductor boost and flyback converters, which adopts active clamp circuit to recover energy stored in leakage inductances of coupled inductor and transformer simultaneously. With this approach, coupled-inductor boost converter can boost voltage of battery up to high output voltage for driving flyback converter, while flyback converter is adopted to step up output voltage up to the desired voltage of capacitated paralysis for convicts conferring. Furthermore, the proposed generator can use single active clamp circuit to recover energies trapped in leakage inductors of two converters. As a result, the proposed generator can reduce cost, weight and size and increase conversion efficiency significantly. Compared with conventional stun gun, the proposed one can achieve 210 ten-second firings which is more than 1.4 times operation of the conventional one. Finally, a prototype under maximum output voltage of 30 kV and maximum output current of 5 mA has been implemented to verify feasibility of the proposed high voltage generator.
