Source: InternetPublisher:风向双子座 Keywords: Operational amplifier regulated power supply circuit BSP output voltage Updated: 2020/05/28
When the input voltage of this power supply is 280-330V, the output voltage is 280V, the current is
25mA, and the stability is <o. 04%. The output voltage is determined by U∞=Ui (鱼无鱼).
In the figure, the transistor VT is a regulating tube; the operational amplifier A is used as a comparison amplifier circuit; the reference voltage is taken from the voltage regulator tube vsl.
