To satisfy the requirement for high voltage and high power applications, a multi-phase multi-level LLC resonant converter with modular structure was proposed in this paper. The voltage stress on the primary switch is only one-nth of the input voltage due to its multi-level structure, the current rating of power devices can be reduced by introducing the proposed multi-phase structure. Using the variable...
This paper proposes a new topology for the soft-switching boost PFC converter. The proposed converter comprises of a transformer, a snubber capacitor, a snubber inductors, three diodes. The primary coil of the transformer is connected to the input side of the converter and functions as the main inductor, and the secondary winding to the snubber circuit. Integrity of the proposed converter is validated...
EEPROM cell with n-well and MIM capacitor is proposed and fabrication is done by using the 0.18??m standard CMOS process. Single polysilicon EEPROM cell applies the stacked metal-insulator-metal (MIM) or n-well capacitor to increase a memory capacity. Although MIM capacitor cell shows a good device performance, it requires a large device-size. N-well control gate cell has an inherent high junction...
