When powered with 230V ac mains, the voltage varies from 0 to |325| volts (100 times per second), and the current follows the voltage and varies from 0 to 325/66 = 4,92 A. The peak power so is 325 x 4.92 = 1600 watts! A single diode can transform AC power into an intermittent DC flow, but a bridge rectifier uses four diodes to reverse the direction of both sides of the AC pulse. With a bridge rectifier, the DC still oscillates from zero to a peak value, but it doesn’t cut out half the time. This method feeds twice the power to a DC output as half-wave 12 Volt DC Systems. Formula: 12 volt inverters require approximately one (1) amp of DC input for each 10 watts of AC output. Example: How many DC amps will a Vanner 12 volt inverter require to operate three 500 watt quartz lights, or a 1500 watt electric heater? Answer: 1) Total watts = 1500. 2) 1500 watts/10 (from formula) = 150 amps. A DC voltage is a voltage that produces, or would produce, DC current, and an AC voltage produces or would produce AC current—and this introduces another terminology problem. “DC” and “AC” are sometimes attached to the word “current,” even though these phrases mean “direct-current current” and “alternating-current current.” For example, if you have 20 watts of DC power and want to know the equivalent AC power, you would multiply 20 watts by 0. 8 to get 16 watts of AC power. This figure is the average power that could be expected from the given DC source. If you are converting from AC to DC power, the equation is P (DC) = P (AC) / 0. 8. A DC to AC converter is called an inverter. Going from 12 or 24 volts DC from car batteries to 120 volts RMS AC is very common. These are usually rated for a couple hundred watts maximum output, but smaller ones are available. In practice, the minimum voltage is about 1.5 volts for any power conversion. qrLti9.
