(1) Ripple Voltage: Ripple voltage refers to the AC component superimposed on the output voltage. It can be observed using an oscilloscope, and its peak values are generally in the millivolt range. Additionally, it can be measured with an AC millivolt meter. However, since ripple is not a pure sine wave, it can lead to some measurement errors.
(2) Voltage Stabilization Coefficient: To ensure that changes in the input voltage of a DC power supply affect the output voltage, it is crucial to maintain a constant load current and surrounding environmental temperature.
(3) Output Resistance: The output resistance of a DC power supply is the same as that of an amplifier. Its value is generally determined by the ratio of the change in output voltage to the change in output current, while keeping the input voltage constant. Examples include a 36V aviation power supply, a 400Hz frequency conversion power supply, 115/200V power supply, 27V DC power supply, 400Hz power supply, and aviation power supply.
