HID-lamp igniter using a two-stage magnetic-pulse-compression circuit

Abstract

This paper proposes a high-intensity-discharge (HID) lamp igniter using a two-stage magnetic-pulse compression (MPC) circuit. The circuit operation is analyzed, and an optimal design procedure for selecting the saturable reactors and energy-storage capacitors is derived. Experimental verification is also given. This igniter can generate voltage pulses whose peak value and pulse width are 50 kV and 800 ns, respectively.
