Innovation enriches high-power diode laser market 02 Oct 2008 The high-power diode laser market is seeing new applications emerge thanks to higher output powers and new emission wavelengths. Jörg ...

Finally, the power diode losses - both on-state losses and switching losses - are examined in a converter circuit, including a comparison of silicon p-n diodes and 4H-SiC Schottky diodes. Learning ...

About five years ago, the power MOSFET industry shifted to a trench-gate technology to reduce the on-resistance. In the trench-gate structure (Fig. 3), commonly referred to as the UMOSFET ...

Intense, the UK-based developer of next-generation modular laser products for printing, defence and industrial applications, has acquired High Power Devices (HPD), US, a manufacturer of customized ...

These 200 A (100 A per diode), single-phase modules feature a low forward voltage of 0.63 V and repetitive peak reverse voltage of 170 V. Additionally, they boast a low leakage current, high ...

As useful as the rectification properties of diodes are, the forward voltage drop they create can vary widely with temperature. This increases losses and can introduce tolerance errors in power ...
