what is inverter? types of it?

Answer 1

An inverter is a circuit for converting direct current (DC) to alternating current (AC). Inverters are used in a wide range of applications, from small switched power supplies for a computer to large industrial applications to transport bulk power.

Inverter Types:

So we have really four different types of inverters (with example products) as follows:

Sine Wave:

Transformer Based (Trace SW series)
High Frequency (Statpower Prosine, Exeltech)
Modified Sine Wave:

Transformer Based (Trace DR Series) :
High Frequency (PortaPower)
Within the Sine Wave category are also four other subclasses:

Sine Wave:

Stand alone (off grid) (charges a battery bank)
Utility Tied Central Inverter with Backup Power (charges a battery bank)
Utility Tied Central Inverter without Backup Power (works without a battery)
Utility Tied Micro Inverter (one inverter for every one or two PV panels. Works without a battery).
Advantages and Disadvantages:

Each of these has a good use and a proper place. Advantages and disadvantages are as follows:

Sine wave units will operate any type of device that can be operated by the utility (subject to maximum load restrictions).
Power from some sine wave inverters is accepted for selling back to utilities under Net Metering programs. Modified sine wave power is never acceptable to the utility due to power quality.
Modified sine wave units will operate MOST devices, but may not operate some laser printers, microwave ovens, battery chargers, portable phones, dimmer switches, audio equipment (may "hum"), and may cause lines on TV's, and cause clocks to operate twice as fast.
Modified sine wave units typically are more basic, and do not have some of the nicer control and monitoring features of a good sine wave unit. Trace brand sine wave units have all components built-in for direct interface to the utility (in most cases), automatic starting of generators, and automatic control of other equipment.
Modified sine wave units are always smaller and lighter than an equally sized sine wave model.
Motors may use more power and get hotter during operation on a modified sine wave unit than they normally do.
Transformer based units have the capability to handle high "surge" requirements. Surges happen when a large load (refrigerator or well pump motor) starts. A high load is created for a fraction of a second. A transformer based inverter can typically surge instantaneously to about 2.5 times its normal rating. A high frequency unit typically has little or no surge capacity beyond its continuous rating nameplate.
For equal nameplate sizes, modified sine wave units typically have higher surge capacity than sine wave units.

Answer 2

According to the definition,

Inverter is a device / system which converts DC power into AC power.

Where as Converter is a device which converts DC to DC.

But coming to the general terminology, an Inverter is an alternative to Generator used during power cuts. This can also be used to operate an AC device like Bulb, TV, etc with available Battery power.

In Inverter generally u'll find 2 types.

1) Offline - most commonly used for household needs, economical and simple in design.

2) On line - used for high power value requirements, expensive compared to offline, but more efficient n reliable.

Answer 3

A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).[1]

The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.

A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process.

In Inverter generally u'll find 2 types.

1) Offline
2) On line

Answer 4

An inverter converts direct current to alternating current. it is also called a logic not gate.

Utility Tied Central Inverter without Backup Power (works without a battery)
Utility Tied Micro Inverter (one inverter for every one or two PV panels. Works without a battery)

Answer 5

An inverter is a device for converting direct current (as from a battery) to alternating current. A typical inverter contains a transformer with a center-tapped primary winding, two power transistors to switch current between the halves of the primary, and suitable drive electronics to run the show.

Answer 6

you could use an inverter to run a home electrical appliance (AC) from your car battery (DC), the only problem being that it has limited wattage, perhaps 100 to 400 watts. enough for a PC but not a vacuum cleaner. See car accessories shops.

PS. I have just realised that there must be an inverter in my computer UPS Uninterruptable Power Supply. It gives 10 minutes power in the case of a mains cut.

Answer 7

inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).
There are 3 major types of inverters - sine wave (sometimes referred to as a "true" or "pure" sine wave), modified sine wave (actually a modified square wave), and square wave. A sine wave is what you get from your local utility company and (usually) from a generator.

Answer 8

I agree with all above , But there are more inverters for example in logical circuit there is a gate that converts 1 to 0 or viceversa .also for phase and ..... it depends what is your question about !

Answer 10

Maybe a little bit, but I suspect the compressor and other cooling items dominate the overall efficiency.
