What is a Pure Sine-wave Inverter?

by admin on May 24, 2013

The output voltage of a sine-wave inverter has a sine wave-form like the sine wave-form of the mains / utility voltage. In a sine wave, the voltage rises and falls smoothly with a smoothly changing phase angle and also changes its polarity instantly when it crosses 0 Volts.

To choose an inverter; you should first define your needs. Where is the inverter to be used? Inverters are available for use in buildings (including homes), for recreational vehicles, boats, and portable applications. Will it be connected to the utility grid in some way? Electrical conventions and safety standards differ for various applications, so don’t improvise.

What is a DC-AC inverter?

May 22, 2013

The utility grid supplies you with alternating current (AC) electricity. AC is the standard form of electricity for anything that “plugs in” to the utility power. Direct current (DC) electricity flows in a single direction. Batteries provide DC electricity. AC alternates its direction many times per second. AC is used for grid service because it [...]

What are the advantages of isolated DC-DC converters?

May 20, 2013

- Safety to personnel, isolation prevents input voltage from transmitting to the output in case of internal failure. – Isolated DC-DC converters can be configured to provide positive or negative outputs from plus or minus rails. – Voltage transients on the input are not transmitted to the output.

What is the difference between isolated and non-isolated DC-DC converters?

May 16, 2013

Isolated dc-dc converters provide full dielectric isolation (no electric contact) between input and output circuits by means of a high frequency transformer, which may be a requirement by certain safety agencies or for certain applications. Typical applications requiring isolated dc-dc converters would be Communications, Forklifts etc.

What is a step-down DC-DC converter?

May 15, 2013

A step-up dc-dc converter is an electronic circuit that lowers the DC voltage level from a higher value to a lower value. Assuming an ideal converter (100% efficiency), Input Power = Output Power Input voltage × Input current = Output voltage × Output current. Thus, a step-down dc-dc converter will increase the input current level [...]

What is a step-up DC-DC convertert?

May 14, 2013

A step-up dc-dc converter is an electronic circuit that raises the DC voltage level from a lower value to a higher value. Assuming an ideal converter (100% efficiency), Input Power = Output Power Input Voltage × Input Current = Output voltage × Output current. Hence a step-up dc-dc converter will reduce the input current level [...]
