Chapter 17 DC to AC Inverters Switched Mode
Inverter output waveforms (either voltage or current) are usually rectilinear in nature and as such contain harmonics which may lead to reduced load efficiency and performance.
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 AC inverter power, P i 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, V i provided to the inverter affects the amount of current drawn.
Traditionally, dc-ac inverters (also known as static inverters) use fixed dc sources to produce symmetrical ac output voltages at fixed or variable frequency or magnitude. The output ac voltage system can be of the single-phase or three-phase type at frequencies of 50, 60, and 400 Hz with a voltage magnitude range of 110 380 VAC.
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.
Common examples are refrigerators, air-conditioning units, and pumps. AC output voltage This value indicates to which utility voltages the inverter can connect. For inverters designed for residential use, the output voltage is 120 V or 240 V at 60 Hz for North America. It is 230 V at 50 Hz for many other countries.
Inverter current, I (A) in amperes is calculated by dividing the inverter power, P i (W) in watts by the product of input voltage, V i (V) in volts and power factor, PF. Inverter current, I (A) = P i (W) / (V i (V) * PF) I (A) = inverter current in amperes, A. P i (W) = inverter current in watts, W. V i (V) = inverter voltage in volts, V.
