Inverter Current Calculator:
Enter the values of inverter power, Pi(W), input voltage, Vi(V) and power factor, PF to determine the value of Inverter current, I(A).
Inverter Current Formula:
Inverter current is the electric current drawn by an inverter to supply power to connected loads. The current depends on the power output required by the load, the input voltage to the inverter, and the power factor of the load. The inverter draws current from a DC source to produce AC power.
The inverter uses electronic circuits to switch the DC input at high frequencies, creating a form of AC voltage. This process involves components like transistors, capacitors, and inductors to shape the waveform of the AC output.
The AC inverter power, Pi required by the load determines how much current the inverter needs to draw from the DC source. This is influenced by the efficiency of the conversion process, represented by the power factor, PF.
The DC input voltage, Vi provided to the inverter affects the amount of current drawn. Higher input voltages result in lower current draw for the same power output, and vice versa.
Inverter current, I(A) in amperes is calculated by dividing the inverter power, Pi(W) in watts by the product of input voltage, Vi(V) in volts and power factor, PF.
Inverter current, I(A) = Pi(W) / (Vi(V) * PF)
I(A) = inverter current in amperes, A.
Pi(W) = inverter current in watts, W.
Vi(V) = inverter voltage in volts, V.
PF = power factor.
Inverter Current Calculation:
- Calculate the inverter current for an output power of 1000 watts, an input voltage of 120 volts, and a power factor of 0.8.
Given: Pi(W) = 1000W, Vi(V) = 120V, PF = 0.8.
Inverter current, I(A) = Pi(W) / (Vi(V) * PF)
I(A) = 1000 / (120 * 0.8)
I(A) = 1000 / 96
I(A) = 10.42A.
- Suppose an inverter supplies a current of 8 amperes with an input voltage of 230 volts and a power factor of 0.9. Calculate the output power.
Given: I(A) = 8A, Vi(V) = 230V, PF = 0.9.
Inverter current, I(A) = Pi(W) / (Vi(V) * PF)
Pi(W) = I(A) * Vi(V) * PF
Pi(W) = 8 * 230 * 0.9
Pi(W) = 1656W.
