Abstract: A negative feedback closed loop circuit composed of an operational amplifier, a main switch, and a current sense resistor is applied to limit the current to a pre-defined threshold whenever there is an overload or short circuit condition is the circuit. A timing circuit composed of resistors and a capacitor is used to provide timing of turning off the circuit. The timing circuit is always charged from the same voltage and started from the same moment of main switching entering into current limit mode. The voltage reference is set by a voltage divider. The timing capacitor voltage and the voltage reference is compared in a comparator. Since both the amplifier circuit and the comparator circuit are temperature independent, the current limiting point and the time delay to turn off the switch are also both independent of temperature.

Abstract: A direct current electrical power system having AC grid power attached to the bus through AC/DC converter, PV panel attached to the bus through DC/DC pre-conditioner, a first direct current load attached directly to the bus, and a second direct current load attached to the bus through a DC/DC converter. The function of the AC grid and AC/DC converter is to create and regulate the DC bus voltage. The function of the PV power is to provide as much power as required to the DC loads. Since the conversion efficiency of the DC/DC pre-conditioner is much higher than that of the AC/DC converter, the conversion loss is greatly reduced if the load is mainly powered from PV instead of AC grid. In addition, a battery can be attached to the bus through a battery charger/controller, which is a bi-directional DC/DC converter.
