ERRORS ASSESSMENT OF THE ELECTRICAL POWER MEASUREMENT WITH VOLTAGE AND CURRENT MODULATION MULTIPLICATION OF PWM-PFM TYPE

V.N. Chinkov, J.A. Belikova
Annotations languages:

The active power measurement method that is based on the combined pulse-width and pulse-frequency ADC is investigated, and the errors estimation of such power meters is given.
Keywords: electrical power, pulse-width modulation, pulse-frequency modulation
