Description

<p>This is a circuit design for a typical wall-plug power adapter.</p>

<p>The sinusoidal source represents a typical US 60 Hz, 120V AC wall supply.</p>

<p>A transformer steps the voltage down to a manageable range to be rectified for a 5V DC supply, but the waveform is still sinusoidal.</p>

<p>The 4 diode bridge rectifier takes this lower amplitude sinusoidal signal and produces a DC biased result, but still with noise resulting from the rectification process.</p>

<p>The capacitor before the voltage regulator chip helps smooth some of this noise. Then the regulator chip provides a self-contained, feedback controlled mechanism to keep the output voltage at the specified value.</p>

<p>The output capacitor further smooths any output ripple and provides a reservoir of charge to supply any surge in current load that may be encountered.</p>

<p>This example includes a load resistor that allows the exploration of the effects of load. The load is varied during the simulation and it can be seen that above a load of 100 mA, the regulation of the output voltage begins to deteriorate.</p>

<p>The addition of a few components can make it possible for such a circuit to provide significantly higher power loads. See http://www.systemvision.com/design/ac-dc-power-adapter-current-boost-regulator for an example.</p>

<p><font><font>A fonte sinusoidal representa uma alimentação de parede típica US 60 Hz, 120 V CA.</font></font></p>

Description

<p>Esse é um projeto de circuito para um adaptador de energia típico de tomada.</p>

<p>A fonte sinusoidal representa uma fonte de parede típica de US 60 Hz, 120V CA dos EUA.</p>

<p>Um transformador reduz a tensão para uma faixa gerenciável a ser retificada para uma fonte de 5V DC, mas a forma de onda ainda é sinusoidal.</p>

<p>O retificador em ponte de 4 diodos recebe esse sinal sinusoidal de menor amplitude e produz um resultado polarizado DC, mas ainda com ruído resultante do processo de retificação.</p>

<p>O capacitor antes do chip do regulador de tensão ajuda a suavizar parte desse ruído. Em seguida, o chip do regulador fornece um mecanismo autônomo e controlado por feedback para manter a tensão de saída no valor especificado.</p>

<p>O capacitor de saída suaviza ainda mais qualquer ondulação de saída e fornece um reservatório de carga para suprir qualquer oscilação na carga atual que possa ser encontrada.</p>

<p>Este exemplo inclui um resistor de carga que permite a exploração dos efeitos da carga. A carga é variada durante a simulação e pode-se observar que, acima de uma carga de 100 mA, a regulação da tensão de saída começa a se deteriorar.</p>

<p>A adição de alguns componentes pode possibilitar que esse circuito forneça cargas de energia significativamente mais altas. Consulte http://www.systemvision.com/design/ac-dc-power-adapter-current-boost-regulator para obter um exemplo.</p>
