The linear current regulator can include a battery; a bus; a transistor having, a base, a collector coupled to the bus, and an emitter; a resistor coupled between a precharge switch and the base; the precharge switch coupled to the battery and the resistor; and a main contactor coupled to the battery, the emitter, and the bus. When the recharge switch is closed, the bus is connected to the battery through the resistor and the transistor so that the bus is charged. When the voltages of the bus and the battery are nearly equal, the transistor turns off, the precharge switch is opened, and the main contactor is closed for normal operation of the vehicle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Linear current regulator for high voltage bus precharging","description":"A linear current regulator is provided for precharging a high voltage bus, such as within a hybrid electric vehicle, in a quick, efficient, and optimal manner.
