采用超级电容器供电的功放电源系统设计

Design of power amplifier power source system using ultra-capacitor supply

为了解决功放变压、整流、滤波式电源的直流电压不稳定和便携式蓄电池电源充电时间长、使用寿命短等问题,分析研究了超级电容器储能系统的优点,提出一种采用超级电容器供电的功放电源系统。采用四个超级电容器组构成两组正负电源,通过智能控制使两组电源轮流充放电,能够很好地解决上述问题,具有良好的使用前景。

In order to solve the instability of power supply＇s dc voltage formed by transformer, rectifier and filter and settle charging long-time, short service life of portable battery power, advantages of ultra-capacitor energy storage system were researched and a sort of power amplifier power source system using ultra- capacitor supply was put forward. By using four ultra-capacitors to compose two groups of positive and negative power supply and making them charge and discharge power in turn through intelligent control, the above problems could be effectively solved and this design had good practical prospect.
