摘要
声频功放设计中,"声系统"是一个重要环节,从声系统来要求功放,使功放参数设置满足方方面面的要求。声系统的要求包括面对声源,放大器最大输入电平要求;功放的非线性失真;功放设计一体化要求等。介绍了功放设计中可靠性设计的要点,包括热设计中电路焦耳热分布和计算;电路稳定性判断。
The ＂sound system＂ is an important segment in the design of audio power amplifier. It is made that the ampli- fier parameters settings meet requirements of all aspects from the sound system. System requirements include the maximum input level facing the sound source, nonlinear distortion, integration design, etc. Reliability design of power amplifier is introduced, including the circuit design and calculation of thermal distribution of joule heat and circuit stability judgment.
