An Isolated Power Factor Corrected Power Supply Utilizing the Transformer Leakage Inductance

A Novel Transformer-less Uninterruptible Power Supply

Uninterruptible Power Supplies (UPS) are finding increased applications with the advent of sophisticated electronic equipment. Low power equipment like FAX machines, Personal Computers, etc., form the major portion of the applications. There is a need for cost-effective, light and sleek UPS in the low power range. In low power UPS, the presence of line frequency magnetic components makes the sy...

Impact of On-Chip Inductance on Power Supply Integrity

Based on product related scenarios, the impact of on-chip inductance on power supply integrity is analyzed. The impact of varying current profiles is shown to be minimal. In a regular power grid with regular bump connections, the impact of on-chip inductance on the cycle average of the supply voltage can be neglected, even for a worst case estimation of on-chip inductance. Whereas, the maximum ...

Flexible Power Electronic Transformer for Power Flow Control Applications

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

Full-chip Power-supply Noise: the Effect of On-chip Power-rail Inductance

The importance of on-chip power-rail inductance in generating delta-I power-supply noise is examined in this paper using systematic circuit simulation of the complete integratedcircuit power net. This source of noise is compared to the resistive IR drop in the net, and to the delta-I noise due to both high-inductanceand low-inductance-bonding packages. Results are presented for a typical on-chi...
