Resistive voltage divider with two stage voltage buffer for harmonic measurement

2012 Conference on Precision electromagnetic Measurements, 2012
The shielding, insulating bracket protection and two stage voltage buffer technology is adopted by resistive voltage divider. It can be used for the harmonic voltage measurement. The ratio error of the voltage divider is within 10 ppm from DC to 10 kHz.

Voltage harmonics generated by voltage-fed inverters using PWM natural sampling

IEEE Transactions on Power Electronics, 1988
The harmonics generated by natural sampled pulse width modulation are investigated experimentally and by theoretical models for the outputs obtained with triangular and sawtooth carrier signals. These equations are valid for synchronous and asynchronous operation.
