摘要
提出一种基于DSP的新型蓄电池充电器开关电源,由DSP取代了单片机,同时还承担脉宽调制,取消了一般开关电源中的脉宽调制集成电路。由于DSP能够对开关电源进行充分地控制,因而也取消了充电功率控制电路。器件的简化能够降低成本,减少功耗,提高设备的可靠性。
A new type Switchmode Power Supply (SPS) for battery charger is introduced . In this SPS, DSP performs PW M without PWM IC and controls directly charging power without power-control circuit. T his SPS is of simple in circuit structure, lower in power dissipation, economical jn cost and high in reliability.
