    摘要: An apparatus for varying the timing of a SMPS, including a microcontroller configured to output a first PWM signal. A converter is coupled to the microcontroller and is configured to receive the first PWM signal and output an analog signal to a SMPS timing capacitor coupled to a SMPS. The analog signal varies the discharge time of the timing capacitor to vary a switching frequency of the SMPS.

    摘要: A power meter for measuring power parameters on one or more electrical power lines/loads is configured to include a revenue class metering module and a power quality metering module. The revenue class metering module and the power quality metering module may use the same measured voltage and current signals to generate revenue accurate power consumption information and power quality information, respectively. The power meter may also include a plurality of filters configured to attenuate high frequency signals included in the voltage and current signals. Each of the filters may be configured with a corner frequency, gain and signal propagation delay that is substantially equal. The filtered current and voltage signals may be received and processed by the revenue class metering module, and the power quality metering module to generate revenue accurate power consumption information and power quality information, respectively. Alternatively, the filtered current and voltage signals may be received and processed by the power quality metering module to generate power quality information, and unfiltered current and voltage signals may be received and processed by the revenue class metering module to generate revenue accurate power consumption information.
