Modern man is governed by his inventions. This is a saying that cannot be taken lightly, as over the course of the past two hundred odd years; mankind has seen a change so drastic that it would’ve been considered impossible even 20 years ago. During the last century, or so saw the advent of electricity and its impact has been monumental to say the least. In the 21st century, almost every part of the world has access to some form of electricity or the other. Yet, there are still places which have a hard time in getting access to lighting. In these areas, inverters play a very crucial role.
The inverter is an overlooked and an underrated invention. It basically converts Direct Current (DC) to Alternating Current (AC) which is used by most devices and machines that run on electricity. In places where power is scarce, an inverter can convert battery or generator power to Alternating Current. In conjunction with a tubular battery online shopping India, an inverter can work to power entire homes.
Apart from its main use as for power backup, an inverter also can be used in many other specific uses. Some of these salient applications are:
- Solar Inverters: These are also referred to as Balance of System (BOS) in a photovoltaic array. These devices can be used for both grid and off-grid systems. They have very specific functions when attached to a photovoltaic system. These functions can include maximum power point tracking and anti-islanding protection. The inverters used are small ones, called micro-inverters. This micro-inverter attaches to individual panels to improve their efficiency and the output from each inverter is combined and then fed to the electrical grid.
- Refrigeration: An inverter can be used in refrigerating by controlling the speed of the compressor motor, which then drives the variable refrigerant flow in an air-conditioning or refrigeration system. This variance in power and speed can help regulate system performance and reduce power usage. This installation is called an inverter compressor. Traditional inverters which used a stop-start cycle are not very efficient. The newer systems utilize a brushless or induction motor whose speed is proportional to the current it receives; a microcontroller then monitors the temperature and adjusts the speed of the compressor to maintain the temperature.
- Electroshock Weapons: Devices used by police or for protection such as a Taser have a DC/AC inverter that is capable of generating several tens of thousands of volts of AC from a single DC battery. The process involves converting the 9V DC battery to 400-2000V DC. This starts by rectifying and then storing current in a high voltage capacitor until a set threshold is reached. After the threshold is reached, the capacitor dumps the entire load on a pulse transformer, which is then stepped it all the way up to its final output voltage of around 20-60kV, enough to send a grown man into shock.
One can utilize inverters for various purposes, but its main use is still the most important one as peoples lives depend on it. One can easily purchase an inverter and tubular battery online.
