What is the Difference Between Power Inverter and Converter?

When designing for specific power inputs and outputs, it is essential to understand the differences between power inverters and power converters. Let us know through this article!

Power Inverter

Power inverter is a DC to AC transformer, which is actually a voltage inversion process with the adapter. The adapter converts the AC voltage of the mains grid into a stable 12V DC output, while the Inverter converts the 12V DC voltage output from the adapter into a high-frequency high-voltage AC; both parts also use the pulse width that is currently used more. The core part is a PWM integrated controller. The TL5001 operates from a voltage range of 3.6 to 40V and features an error amplifier, a regulator, an oscillator, a PWM generator with dead-band control, a low-voltage protection loop, and a short-circuit protection loop.

Power Converter

The converter is also only responsible for one job: converting AC power to DC power. But the term "converter" is very common and you may often see it being misused. For example, if someone says "DC AC converter," this means a logical meaning, although the correct term is "DC AC inverter." AC and DC converters are also commonly referred to as power supplies. There are two common types of converters:

Half-wave rectifiers

These are usually only used in low-power applications because their signals are inherently less consistent. Since half of the AC signal is lost, the output amplitude is about 45% of the input amplitude, which means that the power supply is heavily wasted during the negative half cycle of the input. Even if a large capacitor is placed for the load, there is still excessive ripple during the falling period of the AC input.

Full-wave rectifiers 

Design engineers use full-wave rectifiers to handle this signal loss and get a much cleaner signal. They capture the positive and negative periods of the AC source for applications that require a smooth DC voltage source.

The difference between converter and inverter

An inverter is an electronic device that converts low voltage (12 or 24 volts) direct current to 220 volts alternating current. Because we usually use 220 volt AC to be converted to DC, the inverter works the opposite. We are in a “mobile” era, mobile office, mobile communication, mobile leisure and entertainment. In the mobile state, people not only need the low-voltage DC power supplied by the battery, but also need 220V AC which is indispensable in our daily environment. The inverter can meet our needs.

The power converter converts the information sent by the source for a certain purpose. A matrix converter is commonly used. Compared with the traditional converter, it has the following advantages: no intermediate DC energy storage link; four-quadrant operation; excellent input current waveform and output voltage waveform; freely controllable power factor. Matrix converter has become one of the hotspots in power electronics technology research and has broad application prospects.
