IGBT Definition for Single Ended Induction Heating Cookers

Posted on 29 June 2012

      Cooking with Induction Heating Technology Induction heating is a well-known technology and very commonly used for cooking appliances because of its high energy efficiency. The single ended parallel resonant converter, despite its limitations, is now a well-used topology due to its lower system cost compared with other resonant topologies. The proper selection [...]

Operation Features of Power Semiconductor Devices

Posted on 29 June 2012

      The base of the structure of the semiconductor devices is the semiconductor element defining its electrical parameters and characteristics. The semiconductor element must be well protected from the influence of environment, that’s why it’s fitted into housing ensuring sealing and mechanical strength of the whole structure.

Reliability of Thyristor Technology

Posted on 29 June 2012

      One of the inherent advantages of power semiconductors is increased reliability. Since the introduction of silicon technology in the 1960s, applications have grown from consumer products to heavy industrial products and, more recently, to demanding traction, aerospace and military applications. The reason for the wide acceptance of thyristor technology in expanded applications [...]

Keep Your Distance

      Voltage proof of electrolytic capacitors Aluminum electrolytic capacitors ("electrolytic capacitors," "e-caps") are important components in many power electronics devices today. Ever-increasing requirements for energy efficiency, expanding use of renewable energy and the growing proportion of electronics in automotive applications have driven the wide use of these components. By Dr. Arne Albertsen, Jianghai [...]

Designing for Quality

Posted on 29 June 2012

      Setting the industry standard  The power electronics industry is conservative by nature, and this is by no means a coincidence. The consequences of failure in medium and high voltage power switching applications are simply unacceptable, and this is reflected in the cautious adoption of new technologies. Applications such as traction drives, HVDC, [...]
