Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. Power-control modules are circuits comprising ...

Power control using the linear region of an active device, such as a MOSFET, is not an efficient option. However if the range of power control is restricted to the lower or upper end of the range, ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

Description: Introduction to power semiconductor devices, characteristics, and ratings. Emphasis on analysis and design of circuits with power semiconductors and associated devices. Power ...

A monolithic GaN mains power converter IC was the target of Leibniz University Hannover, which worked with Texas Instruments. And the result is a 15W off-line PSU that can feed a 30-60V LED string ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Part 3 delves into critical equipment for testing today's electronics, and provides updates on circuit-board designs from Part 1. This series installment will address the lab equipment that’s pretty ...
