摘要
通过对当前计算机电源技术中广泛使用的多相PWM开关电源和单相开关电源原理的阐述,并比较了在音频功放中应用的优缺点,并从技术上分析了多相开关电源对大功率功放的供电品质改善的原因。
Based on the principle about multiple-phase PWM switching mode power supply and single-phase switching mode power supply,the advantages and disadvantages of their applications in audio power amplifiers are discussed,and the reasons of why the multi-phase switching mode power supply can improve the power supply quality of high-power audio amplifier are technically analyzed.
