Inductive absorbers address VFD circulating current issues

A problem concerning all motors with VFDs , also known as inverter output, is bearing damage and circulating current caused by high-frequency current, resulting in pitting, frosting, fluting, lubrication breakdown and bearing destruction. Filtering out the damaging current before it reaches the motor, Magnetec's CoolBLUE inductive absorbers reduce transient voltages, straight capacitive currents and common-mode currents.

Proprietary cell technology reduces switching losses

Proprietary cell technology reduces switching losses
Silicon has been made more robust, claims Fairchild Semiconductor, at the announcement of its fourth generation Field Stop (FS) IGBTs. The IGBTs will target solar and battery chargers as well as UPS, where fast switching and low conduction losses can reduce system cost and increase power density.

Power supplies meet medical performance specifications

Power supplies meet medical performance specifications
Excelsys Technologies' Xsolo power supplies have been designed and tested to meet both type B and BF requirements per the IEC 60601 standard. This makes them suitable for applications that need these levels of performance for power supplies used in medical applications. Excelsys’ testing procedures were performed in accordance with requirements for type B (body) and BF (body floating) medical end products.

Power modules address EMC challenges

Power modules address EMC challenges
Power modules engineered for motion control applications have been introduced by Vincotech. The flow7PACK line of power modules includes the flow7PACK 0, rated for 8, 15 and 25A, the flow7PACK 1, rated for 25, 35 and 50A, and the flow7PACK 2, rated for 50, 75 and 100A. The line is a convenient option for applications in which EMC presents a problem because of the PIM module's compact design.

N-channel MOSFETs feature gate capacitance down to 2164Pf

N-channel MOSFETs feature gate capacitance down to 2164Pf
Single n-channel MOSFETs targeted at data networking, telecomms and industrial applications have been introduced by ON Semiconductor. These devices are capable of delivering incredibly low on state resistance, RDS(ON), values, thereby minimising conduction losses and improving overall operational efficiency levels. They also have very low gate capacitance (Ciss) down to 2164Pf, which ensures driver losses are kept as low as possible.

Light-triggered thyristor features integrated protection

Light-triggered thyristor features integrated protection
An optically triggered thyristor that can improve the reliability, lower the system cost and simplify the design of ultra-high-power applications has been introduced by Infineon Technologies. The 6” thyristor incorporates reliable optical triggering, eliminating the requirement for an external electrical trigger circuit. In addition, on-board safety features such as overvoltage protection, dv/dt protection and protection against forward voltage transients during recovery time further reduce component count and design complexity.
