Reinforced DC/DC transformer isolation
16 June, 2010 by Steve Roberts, Recom ElectronicDC/DC converters offer galvanic (input to output) isolation of typically at least 1 kVDC that means the converter will withstand a test voltage of 1000 VDC for one second placed across the input and output pins without the insulation across the transformer breaking down.
The workings of RF transformers - Part 2
03 December, 2009RF transformers are widely used in electronic circuits for impedance matching to achieve maximum power transfer and to suppress undesired signal reflection. Part 2 of this article continues the story that began in the July issue.
The workings of RF transformers - Part 1
03 December, 2009RF transformers are widely used in electronic circuits for impedance matching to achieve maximum power transfer and to suppress undesired signal reflection, voltage or current step-up or step-down, DC isolation between circuits while providing efficient AC transmission and interfacing between balanced and unbalanced circuits such as amplifiers.
Impedance match transformers
01 June, 2009 bySwitchcraft’s 366 and 367 impedance matching transformers are used to convert 110 Ω AES/EBU digital audio signals to 75 Ω signals and 75 Ω signals to 110 Ω.
