Several devices are available to suppress transients that occur in power electronic systems. By employing the appropriate devices, the suppression system can protect the entire power system against transients on ac and dc lines.
A new power supply design uses a combination of chassis capacitors, non-inductive snubber resistors and an inductor to achieve 500mVp-p and 35 dB reductions in output noise and radiated emissions, respectively.
The carrier stored trench-gate bipolar transistor (CSTBT), combined with a light punch through (LTP) structure, provides the optimum combination of low losses and reggedness for industrial power conversion applications.
The latest round of power supply ICs provide new features and better efficiency than their predecessors. Controller ICs provide multiple outputs, single-chip switchers handle higher loads, and charge pump devices deliver higher current...
