The brushless DC (BLDC) motor is becoming increasingly popular in sectors such as automotive (particularly electric vehicles (EV)), HVAC, white goods and industrial because it does away with the mechanical commutator used in traditional motors, replacing it with an electronic device that improves the reliability and durability of the unit. Another advantage of a BLDC …

Generally, electronic devices produce more heat. So this heat should be reduced in order to protect the device. There are many ways to reduce this heat. One way is to switch on the fan spontaneously. This article describes a circuit that automatically, switches the fan when it detects the temperature inside the device greater than …

A buck-boost DC/DC converter delivers a regulated output voltage even when the input voltage is below or above that required by the load. Buck-boost converters adequately serve the needs of battery-powered consumer devices where the required input range is rather narrow; in many cases from 1.8 to 5.5 VDC. However, the situation is different when …

Introduction: A voltage step-up is a circuit that increases the voltage. It can be AC/AC, AC/DC, DC/AC or DC/DC. This voltage step-up is a DC/DC adjustable voltage regulator. Usually a voltage regulator is fed by a higher input than output voltage, for example 9V IN to 5V OUT. This circuit will take a low voltage …
