A power booster, as the name implies, amplifies the input force, power, signal or information into a more distinguishable or useful form. There are so many types of power boosters, and these are categorized as mechanical, pneumatic, hydraulic, electrical, electromechanical, etc. Some examples of power boosters are power brakes, cellular booster, external booster, amplifier, etc.
Let us discuss briefly how this stuff works.
- Power Brake. The power brake system is composed of the brake pedal, levers and shafts, fluid storage and cylinders, fluid linings, brake pads, and brake drums and discs. The input signal or power is the push from your foot which is like telling the system “Hey, I would like to stop this much”. The power is delivered by the levers and shafts to the hydraulic system via a piston that is inside the fluid cylinder. Inside the master cylinder, the power boosting occurs. The piston pushes the fluid into the pipes and in turn these fluids pushes the brake linings into the disc brakes and drums to stop the car.
- Sound Amplifier. This type of power amplifier is composed of electrical components to boost the input sound information to greater power. The input signal here comes from a CD, DVD, flash drive or USB drive, magnetic tape, and other media. The antenna is also a common source of sound signal. The signal coming from these devices is weak and is combined with the sound amplifier’s own power, creating a high-powered signal. The output of the amplifier now has greater power that can drive large speakers of your sound system.
- Cellular Booster. This is a two-way communications booster. It is a solution for homes, offices, and other establishments where a cellular phone’s signal is weak. There are two main parts of this type of booster: the outside transceiver part and the inside transceiver part. The outside transceiver located outside the building accepts and sends signal to and from the nearest cell site as necessary. In receiving data from the cell site, the transceiver outside the building acts as a receiver. It repeats (or amplifies) the accepted signal from the cellular site and delivers it to the inside transceiver through a cable. The transceiver inside the building amplifies the signal even more and sends it wirelessly to your phone. On the other hand, if a phone sends information, the transceiver acts as a receiver. It accepts the data transmitted or sent by the phone, amplifies it, and sends it to the outside transceiver. The outside transceiver will then act as a transmitter. It will further boost the power of the signal and send it to the cell site.
- External Booster. An external booster is used on improving reception of a regular antenna, a satellite antenna, or a GPS. An external booster is a one-way communication signal booster. It is sometimes called a “reception booster”. It accepts signal from your local stations or satellite and improves reception of your devices such as televisions, radios, and GPS systems.
There are many other kinds of power boosters that we encounter every day. As long as a device increases the energy or power input and sends that greater power to the output, that device is considered a power booster.
