AN-1849 An Audio Amplifier Power Supply Design 1 Introduction Analog audio circuit power supplies can have an audible effect in listening tests and a quantifiable effect in bench measurement results. Power supply designs that operate from the power mains are of three common types: Switch mode (SMPS), regulated, and unregulated power supplies.

When a power supply is used with an amplifier, the basic things we need to know before starting are as follows Power output and minimum impedance, or ... Peak / average current Acceptable power supply ripple voltage With only these three criteria, it is possible to design a suitable supply for almost any amplifier.

In audio power supply design, high-frequency noise can couple itself to the audio output, turning pleasant music into irritating noises. A low-pass filter using the correct value of capacitors and inductors prevents any noises above 1 kHz from coupling into audio components. This dramatically improves sound performance.

I have done a large number of designs since then, with output power ranging between 20W to 1500W of output power. I’ve used a number of topologies in the design of these supplies including: • Flyback • Forward • Unregulated LLC Q-Resonant • Regulated LLC Q-Resonant • PFC front end + Unregulated LLC Q-Resonant

The layout of an LPS is deceptively simple: AC Mains –> Transformer –> Rectifier –> Filter Capacitor –> Linear regulator –> DC Mains Obviously different topologies will have different requirements but this is the general layout of an LPS. Let’s break down each piece. SOtM sPS-500 and Paul Hynes SR4

The ultimate Power Supply for Audio: We now have power supply boards to allow people to build their own power supplies. Just choose and install some voltage regulators, add a power transformer, and get either a dual power supply (1 positive and 1 negative output) or a quad power supply (2 positive and 2 negative) regulated output voltages.

POWER SUPPLY DESIGN BASICS by P. ANTONIAZZI In mains-supplied electronic systems the AC input votlage must be converted ni to a DC voltage wthi the right value and degree of stabilization. Figures 1 and 2 show the simplest rectifier circuits. In these basic configurations the peak voltage across the load is equal to the peak value of the AC
