19V 2.64A 3pin laptop AC Adapter for dell
Dell Inspiron Charger
Composition, technical index, characteristic index and parameters of regulated laptop Power Supply
The low ac Adapter stabilized voltage laptop accessories in electronic circuit consists of four parts: laptop adapter transformer, rectifying circuit, filtering circuit and stabilized voltage circuit. Technical index and characteristic index of DC stabilized voltage Computer Charger : input voltage, output voltage, output current, output voltage range
The definition of voltage stabilizing coefficient laptop Power Adapter is the ratio of the relative change of output voltage and input voltage of the voltage stabilizing circuit when the load is fixed. The temperature coefficient st reflects the influence of temperature change on the output voltage; the output resistance ro reflects the influence of load current change on the output voltage; the ripple voltage refers to the effective value of the notebook adapter component at the output end of the voltage stabilizing circuit, which represents the small fluctuation of the output voltage.
