About Booster Regulators

The boost converters or regulators are DC-to-DC power converters that come with an output voltage greater than its input voltage. It is designed with a class of switched mode power supply that contains two semiconductors, a diode and a transistor. Along with this, it also contains storage element, capacitor and inductor and sometimes both in combinatory. The machine is also integrated with filters that are made of capacitors added to the output of the converter to ensure reduction of output voltage ripple. The power for the boost regulators can come from any suitable DC source, including batteries, rectifiers, DC generators and even solar panels. Also known as the DC-to-DC converter with the output voltage more than the source voltage, these are also known as the step up regulators, where in the voltage is stepped up from the source. Since power is always conserved, the output current is lower than the source current.

For improved efficiency, the SMPS switch needs to be turned on and off rapidly, so that there are low losses. Only when the commercial semiconductor switch was discovered in the 1950s, that such SMPSs as the booster regulator became a possibility. All the major DC-to-DC converters were developed during the 1960s where the semiconductor switches were available easily in the market. The aerospace industry needed small, lightweight and efficient power converters which further increased the manufacturing and development of these devices.

The switched systems such as the SMPS model greatly depends on whether the switch is open or close, making its designing process a complex one. It was in 1977, that R. D. Middlebrook from Caltech publicized his models for DC-to-DC converters that are still used today. He averaged the circuit configurations for each switch state in a technique called the state space averaging. This simplified process reduced the two systems into one and this model further propelled the design equation forwarding the growth of SMPS.

Applications of boost converters
The battery powered systems often stack cells over one another to increase the voltage; however, the process becomes inapplicable due to space constraints. The boost converters or regulators comes into play as they can maximize the voltage while reducing the number of cells. Two places where boost regulators are extensively used are the lighting systems and the hybrid electric vehicles. These devices steps up the voltage for example in a lighting system needing 3.3V to emit light, the 1.5V from a single alkaline cell is boosted up and light the lamp.

The functioning mechanism of pneumatic cylinders

A pneumatic cylinder is a type of mechanical device that is used to generate force and is powered by using compressed gas or air. It is also known as an air cylinder. These devices are used to perform a lot of important functions in electronics, automotives, packaging industries, as well as in domestic households. Among their various functions included are the control and regulation of pressure in the air brakes as well as closing certain door types. They also help the car engines to push the pistons and facilitate spinning of the car tires. Although air cylinders are utilized in a diverse range of functions, their basic mode of operation remains the same. In these devices, air pressure is converted into linear motion with the help of a metal piston. Air pushes the piston back and forth, leading to a constant supply of force.

Air cylinders come in a variety of shapes and sizes, and they typically range between 2.5 mm and 400 mm in diameter. Some models of air cylinders have a diameter of 1000 mm, and are intended to be used as a replacement for hydraulics. The air cylinder models that are most commonly used have a tube shaped body with a shaft, a plunger and a rod. The rod fits perfectly into the cylinder shaft, and can be easily moved in and out, and the plunger is attached to the end portion of the rod. The purpose of the plunger is to withstand the impact of air pressure that streams within the air cylinder.

As a way of functioning, a pneumatic cylinder delivers a force by generating kinetic energy from the potential energy present in compressed gas. The kinetic energy thus produced is of scalar quantity and has magnitude but lacks direction. The direction is attained with the help of electrical or manual valves that helps in controlling the direction of the movement. A hand lever or electric solenoid is used to maneuver the directional control valves for keeping adjustable travel rates.As a greater air pressure than atmospheric pressure creates a force which expands the compressed gas, the air expansion propels the piston into moving in a preferred direction. Certain models of cylinders are equipped with cushions on either or both the port ends. The cushions restrict the flow of air to reduce the air travel speed to a lower level.

Pneumatic and its internal structure

There are two main variants of air cylinders, namely single acting air cylinders and double acting air cylinders. The two variants are discussed below in brief:

Single acting air cylinders

The single acting air cylinders are comprised of a single port that is used for compressed air. The port moves in a single direction only, i.e. the cylinders do not retract their pistons after the removal of the air pressure. With the use of spring return hookups, the piston is pushed back to its original position by the spring. However, the device then requires additional air pressure to operate as both the load as well as the spring has been pushed.

Double acting air cylinders

Doubleacting air cylinders are comprised of two ports that are used for compressed air; one of them serves as the instroke and the other one serves as the outstroke. These devices use the force generated by air to expand as well as to withdraw like a vacuum which pulls the rod again inside the shaft, thus needing more air as well as a more complex model of solenoid valve than what is required by thesingle acting air cylinders.

In order to keep the level of performance of these air cylinders intact for many years, it is essential to maintain them regularly. The valves should be checked regularly to make sure that they are inserted properly in the desired positions. If not inserted properly, they may glide over each other and result in a loss of pneumatic pressure. Do not freeze the pneumatic system either, as this can ultimately damage the control as well as the seal functions.

A large number of manufacturers and suppliers deal in high quality air cylinders, and one can get in touch with them from online resources. While buying a cylinder, it is important that a user keeps in mind the motives for which he or she is planning to use an air cylinder.
