This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

The H-Series family of Si diode rectifiers target power supply manufacturers and high-performance systems. The 600-V PFC rectifiers have a reverse-recovery charge (QRR) from 5.9 to 9.8 nC at 25°C and ...

Nexperia has introduced 120V silicon germanium (SiGe) rectifier diodes “with reverse voltages that combine the high efficiency of their Schottky counterparts with the thermal stability of ...

Now researchers in Japan have reported the world’s first continuous-wave UV-B semiconductor laser diode operating at room temperature on a low-cost sapphire substrate. This breakthrough by researchers ...

Alpha and Omega Semiconductor has announced a family of active diodes which can reduce the 1.2V forward drop of 600V bridge rectifiers. “Both products are self-powered from the AC line and do not ...

Linear Technology Corporation announces the availability of a low loss 3-phase ideal diode bridge rectifier reference design, demonstrated on evaluation board DC2465. Conventional 3-phase rectifiers ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...
