# Power Booster to drive a DC motor of 6000watts from a power source of 2000watts Answered

Hello friends, I am a student, undertaking a project. I want to use a power source (AC) of 3000watts (300v 10amps) to drive a DC motor of 6000watts (60v 100amps). Kindly help me with the circuit. yangejnr@gmail.com

The forums are retiring in 2021 and are now closed for new topics and comments.

Don't know why you see a problem here....
Or is there any real laws that prevent us from getting 6000W from a 3000W source? ;)
We are all in lockdown now, so I am sure someone will find a suitable solution to the problem soon.

Thanks Jack :)

One thing you could do is PWM your 2kW to the 6kW in a ratio 1to5 as your receiving motor only has 60V while your powersupply has 300V
Sure, your 6kW motor will only run with 1/5 speed and/or force (Depending on the type of motor you have) but thats about the best you can expect...

I suppose what I wrote previously, regarding conservation of energy, is not going to be all that helpful to you, if you are seriously contemplating building a power converter.

Usually it is easier to buy a converter, than it is to build one.

Moreover the cost of such a converter tends to scale with the amount of power throughput.

I honestly think this is going to be little more complicated than asking a forum, "Can I plz has circuit diagram? Thx."

The only thing I can think of, out there, similar, for which a circuit diagram might be found, might be the power supply for an inverter welder.

I mean, Wikipedia can tell you, broadly, about that kind of welding power supply.

which is a kind of switched-mode power supply,

Regarding circuit diagrams, you could try asking your favorite search engine to show you images of, "circuit diagram for inverter welder"
