摘要： PROBLEM TO BE SOLVED: To shorten the soft start time of a switching power supply.
SOLUTION: A constant current source 13 has an output current larger than that of a constant current source 7. Change-over switches 14 and 8 are closed, respectively, to the contact 1 side and the contact 0 side when operation is started. The constant current source 13 charges a capacitor C3 when power is turned on, and the charging voltage (soft start voltage) V31 rises. A PWM comparator 6 compares a triangular signal S from a triangular wave oscillator 10 with the charging voltage, outputs a PWM signal as the duty ratio increases gradually and performs soft start by switching a switching element 2. When the charging voltage exceeds a reference voltage Vf in a comparator 16, the change-over switches 14 and 8 are switched by the comparison output and the capacitor C3 is charged furthermore to raise the charging voltage thus outputting a PWM waveform. Since the rising rate of charging voltage by the constant current source 13 is higher than that by the constant current source 7, soft start time can be shortened.

解决方案：恒流源13的输出电流大于恒流源7的输出电流。当操作开始时，转换开关14和8分别关闭到触点1侧和触点0侧。当电源接通时，恒流源13对电容器C3充电，充电电压（软启动电压）V31上升。 PWM比较器6将来自三角波振荡器10的三角形信号S与充电电压进行比较，当占空比逐渐增加时输出PWM信号，并通过切换开关元件2进行软启动。当充电电压超过参考电压Vf 在比较器16中，转换开关14和8被比较输出切换，并且电容器C3进一步充电以提高充电电压，从而输出PWM波形。由于恒流源13的充电电压的上升率高于恒流源7的上升速率，因此可以缩短软启动时间。版权所有（C）2007，JPO＆INPIT
