Pure Sine Wave Inverters

The capability supply that is most beneficial for some applications is really a pure 60Hz sine wave, identical to the 120Vrms source available from any power company that is US. All energy that is plug-in that is low are made to make use of this source (high energy devices such as cooking ovens make use of a 240V source) and, as a result, will likely to be most likely to function correctly and a whole lot of effortlessly with this type of supply.

A sine that is supply that is true produced many effortlessly for high power applications through rotating electric equipment such as for instance naval gas-turbine generators, house-hold diesel or gas backup generators, or the different generators utilized by energy companies that make use of shaft torque generate an AC present.

These sources provide a fairly clean, pure sine revolution (lacking significant harmonics and high regularity noise) because of their analog makeup that is rotational. Such equipment that is rotating be inappropriate for low-power backup supply usage for their high expense, big size and upkeep that you need is. An inferior, digital sine that is pure inverter can be extremely of good use as a result.

Applications:

1) Uninterruptible Power Supply (UPS).

2) Adjustable Speed Drives (ASD) for ac motors.

3) Electronic frequency changer circuits used in induction heating, welding etc.

4) HVDC transmission at lower power levels.

5) Renewable Energy such as solar, fuel cell to AC conversion.

6) Electronic Ballast and Compact Fluorescent lamps.

7) Active Filters for power quality improvement.

8) Custom power devices: DSTACTCOM, DVR, UPQC, FACTS: STATCOM, SSSC, UPFC, etc.

Advantages:

1) Low power consumption.

2) High energy efficient up to 90%.

3) High power handling capability.

4) No temperature variation-and ageing-caused drifting or degradation in linearity.

5) Easy to implement and control.

6) Compatible with today's digital microprocessors.

Disadvantages:

1) Attenuation of the wanted fundamental component of the waveform.

2) Switching devices and therefore derating of those devices.

3) Generation of high-frequency harmonic components.

4) Drastically increased switching frequencies that leads to greater stresses on associated.
