I'm using an oscilliscope to take measurements of the line voltage and the phase current. I used a 14 gauge wire to connect the phases together. I measure the current waveform across the 14 gauge wire. I measure the difference in time between the voltage and current waveforms in milliseconds...
Hello, I'm wondering if it's possible to make an alternator run at zero power factor lagging (purely inductive). I was researching this topic and apparently by shorting the leads of the alternator the output will become fully reactive. Yet I've attempted this on a small scale and the most I can...
I have a transformer with the primary winding connected to a 115 volts 60Hz supply, the current is 0.230 amps AC, with a resistance of 25.3 ohms. The secondary winding is connected to an inductive load. The voltage across the secondary winding when the load is connected is 13.14 voltage AC with...
Okay that makes total sense. I can't see whether it's a leading or lagging power factor. If it was a leading power factor it should have a negative sign infront of the power factor number. My meter doesn't show that. So I will need to try to set up the appropriate cap to compensate it fully. I...

That is the site for the power factor correction calculator I used. The voltage I used was 119.6 volts, Current was 0.49 amps, 0.054 Kw, 60 Hz, and a preferred power factor of 1.0. This brought the power factor to 0.921 with...
By tuning, I mean I am manually placing capacitors in parallel with the load. I am using a Kill a Watt power meter and measuring the power factor on the utility end. Before I place a capacitor in parallel with the load I take the measurements of the voltage, current and watts at the applied...
I have an inductive load (120 volts AC at 0.5 amps AC at 60 Hz, 0.9 power factor before correction) that is a connected to the grid. I have been trying to increase the power factor above 0.95, but no matter how much I tune the power factor correction capacitors I cannot increase the power factor...
Thank you for the help, I had a misconception about the functionality of boost converters. I was thinking they increased the overall output impedance of the circuit and load, and since my load does have a reactive component to it I thought it would effect it. But I was able to find an...
Hi, I would like some assistance with a DC to DC boost converter that isn't powering the load I require. The boost converter is one I purchased online. It is a DROK numerical control regulator, 900 watt boost converter.
Boost converter specs
Input voltage DC 8-60 volts
Input current DC 0-15...
I have an AC to DC voltage doubler circuit. I am using a full wave bridge rectifier that uses two diodes and two capacitors that are 470uFarad each. My supply is a 50 watt transformer that outputs 13.9 volts and 3.790 amps. The supply frequency is 60 hz. The output frequency is 120 hz from the...
Hi
The power supply unit is a BK Precision 9110 100 watt multirange 60 volt/5 amp DC power supply.
I will give you the number that is on the top of the mosfet JM34RP LM2577S -ADJ P+. On the board it says SY-DC3403
The load is an inductor that is roughly 11.7 mH at 2.3 ohms DC resistance...
I have a DC to DC boost converter that I purchased. It is a DFrobot DFRO123. I tested the unit by putting a DC voltage supply of 6 volts in the Vin terminal and connected the negative of the supply to the ground terminal. Then I connected a volt meter to the Vout and ground terminal. The boost...
Thank you everyone for your assistance. With the suggestion to add a high resistance in series with the supply, do you mean to add that resistance in series with the primary winding of the transformer? The primary winding has a resistance of 25.5 ohms and a reactance of 168.96 ohms. Correct me...
I have a very basic question for the professionals here, but I am having a small issue with my parallel LC circuit. I have an inductor that is 6.425mH, a capacitor that is 217uF (it is two 470uF aluminum electrolytic caps connected in series to make one non-polar 217uF cap). I am supplying the...
Thank you everyone for the help! The suggestion from Jim Hardy has been very useful. I have started to graph the supply voltage, current, inductor voltage and capacitor voltage with different input frequencies. It has shown that I am quite a bit below resonance with this setup. Thank you to all...
