the rated output  voltage. This error is the superposition value of line stability and load stability. Normally this parameter at  +/-1% line stability is the percentage of the output voltage that deviates from the rated voltage when the  input voltage varies between the maximum and minimum allowable range. Load stability is the  percentage of the output voltage that deviates from the rated voltage when the output load current  varies between the maximum and minimum allowable range. Efficiency: The ratio of total output power to active input power, expressed as a percentage. That is,  efficiency = output power/input power *100%. Rated power: refers to the maximum output power of the power supply (voltage V times current A). Electromagnetic compatibility (EMC) : the ability of a device or system to operate as required in its  electromagnetic environment without producing intolerable EMI to any device in its environment. EMC includes EMI(electromagnetic interference) and EMS(electromagnetic tolerance). The so-called EMI  electromagnetic interference refers to the harmful energy transmitted or radiated by the switching power  supply. And EMS refers to the ability of the switching power supply to be unaffected by the surrounding  electromagnetic environment in the process of performing its due functions. Ripple: as the dc stable power supply is generally formed by the ac power supply through rectifying and  voltage stabilizing links, it is inevitable that there are more or less ac components in the dc stable power.  The ac component superimposed on the dc stable power is called ripple. Output ripple and noise: the amplitude of the output ac voltage from the switching power supply within  a specified bandwidth, usually expressed as a millivolt level peak-to-peak or RMS value. Total Harmonic Distortion is refers to the signal source input, the output signal (harmonic and its  frequency doubling component) than the input signal of the additional harmonic component, usually  expressed as a percentage. Generally speaking, the total harmonic distortion of this frequency of 1000Hz  is the smallest, so many products take the distortion of this frequency as its index. So the test for total  harmonic distortion is 1000Hz sound, and the smaller the better. Overshoot and undershoot: Overshoot is when the first peak or valley value exceeds the set voltage -- the  highest voltage for the rising edge and the lowest voltage for the falling edge. Undershoot is the next  valley or peak. Excessive overshoot can cause the protective diode to work, leading to premature failure.  Excessive undershoot can cause false clock or data errors. Working environment temperature switch power supply can be reasonable electrical indicators and  stability of the working temperature range. Unless specified otherwise, do not assume that the switching  power supply can output full power throughout the temperature range, nor that the switching power  supply can maintain the same electrical specifications throughout the operating temperature range. Pulse Width Modulation (PWM) : a method of voltage regulation used in switching power supplies by  simply changing the period and duty cycle of the pulse train. I
