Lithium-ion Battery is Powering the Future

The 2019 Nobel Prize in Chemistry awarded to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino “for the development of lithium-Ion batteries.” Their research has made a fundamental contribution to the development of rechargeable batteries that we use in many consumer products. Lithium-ion batteries are also considered a possible solution for the development of…

The Need for Power Control

The development and innovation of new power systems in the industrial sector, electric motors, and relative control require discrete high-performance components. In recent years, the power electronics semiconductor market has seen a rapid growth, mainly due to increased sales of IGBT devices for electric/hybrid vehicles (EV / HEV) and motor drives. MOSFET demand is driven…

Microcontrollers for Motor Control Systems

Some microcontrollers have been designed to simultaneously control more than one permanent magnet motor in equipment such as air conditioners, washing machines, and dishwashers. Moreover, industrial applications such as general-purpose inverters, uninterruptible power supplies (UPS) as well as heating systems, ventilation systems, and temperature conditioning applications can implement various MCU solutions. Nowadays microcontrollers (MCUs) represent…

High-performance DC motor drivers

Motor control has long been at the forefront of research and development activities, aiming at finding effective and efficient microelectronic solutions. The purpose of a motor controller is to be able to manually or automatically act on the electric motor (start-stop, advance-inversion, speed, torsion, and protection against voltage overloads). The integrated circuits (ICs) for motor control…
