Integration and Test of a Dual Purpose Pulse Forming Network into the P&e Hwil Sil

A Dual Purpose Pulse Forming Network (DP-PFN) has been developed to power both the Electro-ThermalChemical (ETC)/Electro-Thermal-Ignition (ETI) lethality capability and the Electro-Magnetic Armor (EMA) survivability capability improvements envisioned for future hybrid-electric combat vehicles. The DP-PFN is capable of providing two types of energy pulses to accommodate gun and armor loads: extremely short pulse lengths for the EMA, or longer pulse lengths for the ETI/ETC Gun. This capability of the DP-PFN allows for emulation of three major hybrid-electric, lethality, and survivability functions of an electrically-driven ground combat vehicle. Recently, an advanced first-generation DP-PFN for driving both ETI/ETC and EMA emulators has been integrated into the Power and Energy (P&E) Hardwarein-the-Loop (HWIL) System Integration laboratory (SIL) in San Jose, California. This paper describes the DP-PFN integration and testing in the SIL. In addition, this paper describes the design and the build plans underway for integrating a second-generation Variable Pulse Forming Network (VPFN) into the SIL. The VPFN will augment the SIL’s capabilities for forming a wide variety of pulse waveforms while providing both enhanced high density energy storage and fast recharge capabilities. .
