For example, at PRAN Systems Inc., most of our products with transistorized outputs are protected by circuits that occupy this specific function. Protection against overcurrent and lifespanĪnother great advantage is that some transistors are protected in the event of a short circuit. PWM is commonly used to control the speed of a DC motor or the brightness of lighting. The MOSFET makes it possible to control this output power by varying its activation and deactivation times, something that a simple relay cannot do. The longer the switch is on versus off periods, the greater the total power supplied to the load. The average value of the voltage supplied to the load is controlled by turning on and off the switch between the supply and load at a rapid rate. Pulse width modulation (PWM), is a method of reducing the average power delivered by an electrical signal. In addition, they are silent and do not indicate if they are activated. Since it is non-mechanical in nature, it can provide much faster switching compared to relays. What are the advantages of adopting a power distribution controller equipped with MOSFETs?Ī power MOSFET is much smaller than a relay and can also be used as a fast switching device. However, the opportunity remains and is more justified than ever, in particular for bodybuilders of emergency or public utility vehicles. The reasons are multiple: lack of understanding of the technology, simplicity of the current system to operate, power required too high or the perception that the technology would be more expensive. However, many manufacturers of specialized vehicles or mobile equipment are still reluctant to abandon the use of conventional relays and migrate to completely electronic and self-protected control systems. The western world has adopted this technology more widely than the rest of the world. In a way, they play the same role as a switch (such as a traditional electromechanical relay), but with advantages that often surpass the latter. In electronics, its function is to convey the necessary voltage to a load.
A Metal Oxyde Semiconductor Field Effect Transistor (MOSFET) is a semiconductor device belonging to the family of transistors.
