摘要: An electronic watthour meter including a pulse width modulation circuit for converting voltage signal proportional to the load across power supply lines duty cycle and current-to-voltage converter current signal. A multiplication issues product of signals under control as instantaneous consumption lines. filter integrates an integrated voltage-to-frequency converts automatic compensation feedback input thereby eliminating inherent offset caused by circuit, converter.
