Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

Figure 1: Permanent Magnet Synchronous (PMS) motors are commonly used in industrial applications because they natively offer higher torque at lower speeds

MCU Innovations Respond to Motor Design and Applications

Patrick Heath, Microchip

Motors come in many forms. They range from stepper motors that are often used in precision positioning applications to the large Alternating Current Induction (ACI) motors often employed to deliver high torque for industrial mixing and processing. Very often, the choice of motor is not just determined by the ap

Ensuring IoT Infrastructure Integrity via Smarter Nodes

Mark Patrick, Mouser Electronics

IoT infrastructure can potentially be compromised in a number of ways. Firstly, there is the possibility that IoT nodes could be damaged during shipment or transport, prior to their installation. Then they might be exposed to harsh conditions, due to the application environment in which they are located - with extreme heat, high humidity or vibrational forces al

Battery Solutions for IoT Devices

Mahoro Takahashi, Product Manager – Micro Batteries. Murata Electronics Europe

There is no question that the Internet of Things (IoT) is growing very rapidly, with estimates of nodes deployed in the billions. Many estimates suggest that there are now up to six IoT nodes for every person on the planet – and the growth rate is accelerating. On the other hand, there are those who sugge
