Can a DC to AC inverter with 230 VAC output voltage be connected to an AC to AC inverter to get 3 phase 460 VAC output voltage from a 720 VDC battery pack at 60 amps?

It would make no sense even if you could find a DC-AC inverter with an input voltage of 720V. The efficiency would be horrible and the bulk of the equipment would be impractical. The voltage your motor expects is 460 VRMS. This translates to a peak voltage of 650V (1300V peak-to-peak). Your battery pack, switched through an H-bridge of IGBT's using a PWM scheme could directly feed the motor. This is the best method available, but the design would not be trivial. Possibly, you could ditch the DC-AC inverter and use just a 460V variable-speed drive with 460V input and 460V output. Bypass the input rectifiers on the drive and use your batteries DC output directly to power it. It's a possibility anyway. You realize, of course, that you are dealing with voltage and power levels that can be fatal, right? Be careful.

Why the transformer connected on inverter output?
A transformer is connected to the output of inverter in order to step up the AC voltage output.
Introduction of DC to ac inverter?
A DC to AC inverter takes a DC voltage input to a AC voltage output. So if you have a 12v battery and need to run a 120v AC tool or something. All you need to do is plug a inverter to your battery and plug your 120v tool the the inverter. Takes all there is too it.
Why does the output wave shape give spike voltage in push pull inverter?
Due to inductance there is a spike in output voltage
What is the total voltage of a battery containing five 2 V cells connected in series?
Total voltage output of 5 2v cells connected in series would be 10v
What two factors determine the output energy of a battery?
The energy delivered by a battery would depend on-- the battery's voltage-- the resistance of the load connected across its output terminals-- the length of the time the load is connectedThe power delivered by the battery is [ (voltage)2 divided by (load resistance) ].The total energy delivered by the battery is [ (power) multiplied by (time the load is connected) ].
Is there a way to increase the output amps of a source like battery by using some device?
just get a inverter that will increase the voltage by quite a lot well the current anyway.
Does harley voltage regulator get a breaker before wired to the battery?
No. The DC output from the voltage regulator is connected directly to either the positive terminal of the battery or the hot side of the starter relay on some older models.
Can you hook more than one solar battery charger in series to charge a 36 volt system?
It is important for solar battery charger output voltage to match voltage of battery system being charged. Voltage is additive in series circuits, therefore 3 12VDC solar battery chargers connected in series would provide correct output to charge a 36VDC system.
Can you use inverter to start the dc starter?
Yes. As long as the output voltage is direct current and matches the starter's voltage requirement (IE) 12volt, 24 volts etc. As a matter of fact, That is what a common automotive battery charger does!
How can you know that a 1000 watt inverter can power a 700 watt microwave?
FOR INSTANT ANSWER IS YES AND YOU STILL HAVE 30% ALLOWANCE. BUT TO BE SURE YOU WILL FINISH COOKING YOUR FAVORITE FOOD YOU HAVE TO ANSWER THE FF. BASIC QUESTIONS. 1. WHAT IS THE INPUT VOLTAGE OF INVERTER - IS IT THE SAME FROM YOUR CAR OR CHARGER? 2. IS THE OUTPUT VOLTAGE OF INVERTER SAME AS YOUR MICROWAVE INPUT VOLTAGE? 3. WHEN YOU ARE CAMPING BE SURE THAT YOUR CAR ENGINE IS RUNNING OR ELSE YOU WILL HAVE YOU BATTERY DRAINED. ENJOY YOU MEAL...
Voltage frequency inverter dc or ac output?
An inverter changes a d.c. input to an a.c. output. Inverter is a device to change low volt DC to high volt AC 12 Dc to 220 Ac volt So many type of inverter of watts 500 watt 1000 watt 5000 watt
To increase voltage output when using more then one battery connect the batteries in?
To increase voltage output when using more then one battery connect the batteries in series.
