  • Patent number: 5982594
    Abstract: An intrinsically safe power supply unit is provided for conditioning power supplied by a power source. An input power converter connected to the power source receives current from the power source. A direct output crowbar and discrete impedance elements dissipate and limit the energy in the power supply unit that would otherwise be delivered to an external fault. In addition, the direct output crowbar extracts energy from any external storage elements. An adaptive shut down circuit distinguishes nominal load conditions including load changes from an external fault. A multistage LC power filter is used to minimize the stored energy that would be deliverable to an external fault or dissipated by the direct output crowbar and discrete impedance elements. The combination of the direct output crowbar, discrete impedance elements, adaptive shut down detection circuitry and multistage LC power filter significantly improves the level and quality of intrinsically safe power delivered by the power supply unit.
