High Voltage Power Supply with Dual Output Power Supply in Amplifier

High Voltage DC Power Supply

The Power Amplifier must use a high power supply circuit, due to great sound must also be supported with power (power supply) that great anyway. In the power amplifier 1000W (500W (L) and 500W (R) can work if driven by transformers least 30 A less. Diode bridge and Electrolyte Capacitor (Elco) must have a value too big. Average power amplifier can work if given the power consumption of the toroidal transformer between 2 x 48VDC power supply to 2 x 80VDC, or more. When we sum 48 + 48 =  96, 80 + 80 = 160 Volt. Of course it's very high voltage power supply.

Indeed, the power amplifier can reach 40 kg weight. But now some products speaker / Power Amplifier system known already implemented switching power supply with electronic methods. imagine if there is an active speaker / power amplifier transformer that uses ordinary (conventional), weighing up to 40 kg, but the active speaker / power amplifier system that uses switching power supplies only 20 kg.

Dual Power Supply with One Transformer

Ok, we return to the dual power supply of conventional systems. In the big power supply to the amplifier used transformers worth between 5-30A with voltage 48-80V, and the other one is 2 x 15V in different cable.
Bridge diode and elco have big capacity. The Bridge diode adapted to the size of transformers, ranging Electrolyte Capacitor 2 x 4.700 uF to 2 x 10.000 uF with voltage 63-160V. Used to filter capacitor 100nF. The power supply system using symmetrical power supply.
sometimes equipped with dual output transformers are symmetrical, i.e the first 2x24V10A secondary, secondary and two 2 x 15V 1A, for example.
the second secondary (2x15V) used for Pre Amp Amplifier OP. TRANSFORMER CT connection is usually connected to the grounding (box).
But do not directly connect the grounding cable to the CT, because it will cause hum. Wiring must be correct, the wiring system distributed by the regulator power supply to each  to grounding equipment.
