Reinforced DC/DC transformer isolation
DC/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
RF 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
RF 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.
