Um estudo simples dos estágios de um power supply. Transformador Retificador Filtro Regulador Calcular R1 Estou assumindo um transistor NPN 2n2222. Para entrar em saturação ele precisa de 15mA, então calculo: R = (Vin-VBE)/IB R= (17.7RMS-0.7)/0.02 R=845 ~ 820 Para calcular R2 R=(Vin-Vled)/ILed R = (11.2-2)/0.02 R=460 ~470
