With Capacitive Power Supply (CPS) technology, the real wattage is the LOAD amperage and voltage; not the SOURCE amperage and voltage.
For a battery charger the ‘load’ is the battery; so you measure the amperage going into your battery and the voltage of the battery to get the actual wattage being drawn from the source.
With a CPS, the ‘source’ voltage and amperage is irrelevant; but conventional training assumes that voltage and amperage are the same in all parts of a circuit.
For a CPS, that simply is not true because:1. The capacitor separates the source voltage from the load voltage. The load voltage will depend on the capacitive reactance and the load resistance. ‘Excess’ voltage, (more than the load needs) is returned to the source every alternate cycle.2. The maximum amperage is controlled by the capacitive reactance.
A wattmeter (on the source) will confirm that the true wattage is the load voltage and amperage.
Anomolies that confuse people who are used to ‘conventional’ circuits:
1. If the load has zero or very low resistance, the ampmeter will still show full amperage flowing through the circuit. For example: a simple Capacitive Amperage Limiting curcuit (one of the CPS options) using a 25 uF capacitor (fed by 120 VAC 60 Hz) in series with a shorted battery will show 1 amp flowing in all parts of the circuit. A ‘conventional thinker would assume the wattage to be 1A x 120V = 120 watts. The actual wattage will be zero because the load voltage will be zero; so the wattage is 1A x 0V = 0 watts. A wattmeter wheel will stand still because all the power that is going into the circuit is being returned on the alternate cycle.
2. If using a Capacitive Transformer (another version of CPS) you may read one amp flowing in the high voltage side of the circuit and many amps flowing in the low voltage side. Since ‘conventional’ thinkers are not used to using capacitors as transformers, they may think the higher amperage is ‘Free Energy’; but it’s not. Just as in an inductive transformer, voltage has been converted to amperage. The CT transforms with no noise, vibration or heat losses. The actual wattage of the CT still depends on the load resistance, zero resistance = zero wattage, regardless of the amperage flowing back and forth.
