AC/DC Thermal Converters of the ETL
IEEE Transactions on Instrumentation and Measurement, 1974In order to establish alternating current and voltage standards, various types of thermal current and voltage converters have been constructed. From their detailed analysis, the specifications and characteristics have been determined. These converters have been used in a circular international comparison.

A TSV-based architecture for AC-DC converters
2013 8th IEEE Design and Test Symposium, 2013In this paper, a proposed through silicon via (TSV) structure is used to construct AC-DC converters. This structure is analyzed using 3D electromagnetic full-wave simulators. The results show that the proposed 3D converter exhibits small area with superior performance compared to a 2D transformer, for the same footprint as lossy substrate effects are ...

A Novel DC-AC/DC Converter with Boosted AC-DC Output Voltages
2020 11th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC), 2020A single-input double-output converter, which receives a DC voltage and supplies an AC and a DC load, is introduced in this paper. The topology is based on merging a half-bridge DC/AC inverter with a conventional DC/DC boost converter. The DC load supplied in one of the output terminals experiences an increased voltage level compared to that of the ...

Stable wideband ac–dc converter
Review of Scientific Instruments, 1982This paper describes improvements on a stable wideband ac–dc converter, which is basically composed of a dual junction field effect transistor and a low drift operational amplifier. This converter has a stable square-law transfer characteristic up to 200 MHz for 0–0.5 V output with a drift of less than 0.1 mV/h.

AC/DC converter free LED driver for lightings
2012 IEEE International Conference on Consumer Electronics (ICCE), 2012This paper presents a noble AC/DC converter-free LED driver for LED lighting applications. The presented LED driver applies the AC mains power directly to the LED strings with no AC/DC converter stage, thus bulky transformer and life-time limiting electrolytic capacitor no longer needed.
