Design and implementation of a high efficiency power supply for use with a high power audio amplifier
This paper presents the design and implementation of a high power, high efficiency, switch mode power supply (SMPS) suitable for use with a high power audio amplifier. The power capabilities are sufficient to drive a load of 300 watts continuous load per channel, for two channels, totaling 600 watts. High power switch mode design methodology was researched to identify critical areas unique to high power, high frequency and high voltage designs. Also identified are the design techniques applicable to high power design. A review of switch mode power supply design versus a linear design will be introduced with the comparative benefits and disadvantages of both. The sub sections of the SMPS are discussed with particular regard to high power & voltage applications. Issues of measurement are also discussed which may not be apparent to the novice. The paper details methods suitable for many high power designs within the limitations of available components from manufacturers. Test results are presented for DC loads and dynamic loads.
