3.4
Total distortion ratio totaldistortionratio; TDR
The ratio of the root mean square value of the total distortion content of an alternating variable to the root mean square value of the fundamental component or reference fundamental component.
Note. The total distortion rate depends on the choice of the fundamental component. If the fundamental wave component used cannot be clearly known from the context, it should be explained.
3.5
Power efficiency
The ratio of the output power of the converter to the input power.
Note 1.The variable current factor does not consider the power of the AC component on the DC side, and the power efficiency is included. Therefore, for AC and DC converters, the
The value of the factor is smaller than the value of power efficiency. For a single-phase two-pulse (full-wave) resistive load converter, the theoretical maximum value of the variable current factor is
0.81pu, and the ideal maximum power efficiency is 1.0pu.
Note 2.The variable current factor can only be correctly obtained by measuring the AC fundamental power, DC voltage and DC current. Power efficiency can be measured by measuring AC power and DC
The power can be obtained correctly by calculating or measuring the inherent loss.
Note 3.The active power on the AC side (average power) and the average power on the DC side should be considered.
