Uc3907 Load Share Ic Simplifies Parallel Power Supply Design
نویسنده
چکیده
Many power supply manufacturers have found it economically feasible to make standard modular power supplies which are easily paralleled for higher current applications. If special provisions are not made to equally distribute the load current among the paralleled supplies, then one or more units will hog the load current leaving the other units essentially idle. This results in greater thermal stresses on specific units and a reduction in the system reliability For example, reliability predictions will indicate that a component operating at 50 degrees above ambient will have one-sixth the lifetime of the same component operating at 25 degrees above ambient [1].

Design of power-efficient adiabatic charging circuit in 0.18μm CMOS technology
In energy supply applications for low-power sensors, there are cases where energy should be transmitted from a low-power battery to an output stage load capacitor. This paper presents an adiabatic charging circuit with a parallel switches approach that connects to a low-power battery and charges the load capacitor using a buck converter which operates in continuous conduction mode (CCM). A gate...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

Microsystems must conform to microscale dimensions, store sufficient energy to last extended periods, and supply enough power to sustain, among others, wireless and sensor functions. Because batteries source moderate power with low energy densities, miniaturized devices benefit from deriving energy from fuel cells (FCs) and power from Li ions, rather than relying on one source and over-sizing i...

In recent scenario many appliances requires DC power supply. Hence to obtain the DC power from input ac supply, Power Electronics circuits like Rectifiers which is a non-linear load has to be used. The current drawn by these non-linear load will be phase will not follow the supply voltage (i.e non sinusoidal). This results in a High Total Harmonic Distortion (THD) and Low Power Factor (PF).
