To improve the energy quality, most of the renewable energy systems include an energy storage element charged by the bidirectional DC-DC converter. This paper proposes the bidirectional DC-DC converter which employs the two bridge configuration resonant class-E converters on the both sides of the isolating transformer. The low side converter is controlled as step up and the high side converter ...

This paper presents an ultrafast CMOS flash A/D converter design and performance. Although the featured A/D converter is designed in CMOS, the performance is compatible to that of GaAs technology currently available. To achieve high-speed in CMOS, the featured A/D converter utilizes the Threshold Inverter Quantization (TIQ) technique. A 6-bit TIQ based flash A/D converter was designed with the ...

Abstract: In this paper a new topology of high step-down dc-dc converter is proposed. The proposed converter uses an interleaved structure with one phase using a traditional buck converter and the second phase uses its inverted version. By this technique a high step down voltage conversion can be achieved as compared to the traditional interleaved buck converter. Operating principle and steady ...

We have developed a new isolated AC/DC converter for electric vehicle on-board chargers. It consists of an AC/DC converter with Gradationally Controlled Voltage Inverter (GCVI AC/DC converter) and an isolated Zero-Voltage-Switching (ZVS) DC/DC converter, each of which is optimally controlled to convert in a highly efficient means. As a result, the new on-board charger has achieved a power conve...
