Energy savings apparatus

In combination with a 100 volt ac voltage source, an electrical power metering means, an error compensating circuit means for accurate measurement of actual power consumption and an associated electrical load having power supply circuit for feeding current to said load, a power supply circuit means for conducting current from the ac voltage source to said load in alternate half cycles, the improvement comprising:

• first circuit means for conducting current in one direction through the load in a first half cycle and second circuit means for conducting current through the load in the opposing direction in a second half cycle, said first and second circuit means being responsive to the positive and negative cycling of the ac voltage source so that current is conducted in the first half cycle in an out-of-phase relation to the current conducted in the second half cycle, a switching control means having a first switch means responsive to the positive half of the sinusoidal voltage waveform from the ac voltage source for energizing said first circuit means and a second switch means responsive to the negative half of the sinusoidal voltage waveform from the ac voltage source for energizing said second circuit means, and a voltage delay elimination means for controlling the switching of the second switch means by monitoring the current load demand to eliminate time delay in the current flow in the second circuit means for providing the negative half wave of the sinusoidal waveform to the load without the occurrence of a time delay such that a complete sinusoidal waveform is instantaneously presented to the load.
