first excuse me for my english.
I need a desing of +/- 70v 5A power supply for a power amplifier.
I have a toroidal transformer 50+50v . may be help me? filtred and if posible regulated.
thanks |

Hi,
regulated won't works, the sec voltage of the trafo is too low, you may need 2*60-70V for that. Anyway regulated voltage is not needed to feed an amp in most cases.
So you need a 25A graetz-bridge, and two 10000uF/80V cap. That's all. |

| is better to put 4 x 4700uf 80v caps? or more. |

| Using more capacitance reduces voltage ripple. On the other hand, using more capacitors of a smaller value (yielding the same total capacitance) may sometimes improve performance if the combination produces less ESR and ESL (equivalent series resistance and inductance) or features a higher total ripple current rating in comparison with a single capacitor. |

is this a good desing of power supply for power amp?
is too big the capacitance of caps than the only 10000uf ?
anything changes in this desing?
i need help |
