(1) Ripple Voltage: Ripple voltage refers to the AC component superimposed on the output voltage. It can be observed using an oscilloscope, which typically shows values in the millivolt range. It can also be measured with an AC millivolt meter. However, since ripple is not pure, it can lead to certain measurement errors.
(2) Voltage Stabilization Coefficient: To ensure that changes in the input voltage of a DC power supply cause corresponding changes in the output voltage, it is crucial to maintain a constant load current and ambient 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, with the input voltage remaining constant. Examples include a 36V aviation power supply, a 400Hz frequency converter power supply, 115/200V power supply, 27V DC power supply, 400Hz power supply, and aviation power supply.
