An energy-to-pulse (E2P) converter for converting analog voltage and current measurements into digital power consumption readout that has an improved output frequency range and can eliminate the potential information loss in a multiple-wires and multiple-phases power distribution system without added complex hardware. The E2P uses a threshold value T in determining the output pulse count which represents the energy/power consumption. The energy consumption E is updated every cycle of a first clock rate F1 during which a power P calculation is performed following a voltage V and a current I analog-to digital conversion. The updated energy consumption E is then divided by the threshold value T to determine the number of pulses that correspond to the power consumption. The number of pulses are output at a second clock rate F2. In so doing, more than one pulse can be generated for each P calculation thereby improving the output frequency range. To prevent complete signal overlaps that may lead to information loss in multiple-wires and multiple-phases power system, the pulse output for each wire can be programmed to have a different phase such that the pulses from the pulse outputs, which are all synchronous with each other, are non-overlapped.
