At the end of the 19th century, advances in the semiconductor technology introduced solid state switches. These type of switches replaced the older models that were being used before. Such models included thyratrons, ignitrons, and spark gaps. Before the invention, electronics used older drivers which have since been replaced by TTL input controls that have dramatically improved performance and efficiency. A high voltage contactor has been used a lot in the past few years and there are a lot of details that make them stand out.
One of these details is the low input power loss. This low loss has been making possible through the use of MOSFET technology when developing the switches. The only loss incurred in this technology is only caused by the total gate charge, the drive voltage, and switching frequency. The loss is very low since the overal gate charge is small. Switches that use bipolar transistors such as BJT tend to cause more losses. There is a lot of power lost especially during switching.
These are the most reliable and efficient switches when it comes to current equipment. Most of this equipment requires a steady saturation even when short circuited. In switch mode supplies, these contactors use smaller inductors because switching is done at fast speeds. This greatly improves the overall efficiency of the contactors. The reliability they offer has made them the best choice for high current equipment such as medical test equipment.
It is possible to easily customize these switches in a number of ways. This may include the housing and footprint. The sensitivity can also be customized as per customer needs. This customization helps to suit applications where the switches are being used. They are also easy to use due to the galvanic isolation with TTL control.
The switches have been designed to prevent cases of overload or voltage reversal. Voltage reversals have been causing adverse effects which makes them safe for use anywhere. The technologies used in these contactors reduce risks that come with handling the current.
Little current is required during switching which is essential in preventing heating, especially when handling high loads. This is mostly because the contactors are power controlled. Other contactors require a fair amount of current to switch. This causes a lot of heating when handling a lot of power. This may cause such switches to operate on linear mode because the level of the drain current affects the gate-source voltage. This is not the case with the power switches, level of drain current has no effect on gate-source voltage.
These switches guarantee faster switching. The speed advantage of these contactors makes them a better choice for everyday use. They are able to handle high frequencies due to the thin oxide layer used when making the transistors. This layer prevents the use of current when switching. Most switches especially those that use bipolar transistors take much time when switching.
There are many developments still being made in the semiconductor technology in order to reduce limitations if these contactors. They are efficient enough to be used in day-to-day operations but still have a few downsides that need to be taken care of. The above-discussed features are just some of the advantages of using these switches. These are sure to make your work easy.
