In literature, the details of engineering power converters are often discussed in a limited scope. However in practice, the design of such converters entails consideration of the whole circuit as the many subsystems of are inevitably linked together. This paper presents a scripting method to assist in the design of large power converters. Such an approach simplifies iterations in the design process...
In recent years, 380V power distribution systems have been attracting attention as high-efficiency and high-reliability power systems that can be used in telecommunications buildings and data centers. The move toward the proactive use of natural energy, meanwhile, has also been gaining strength. Against this background, we have been moving forward on the construction and experimental study of a container...
Design considerations and performance evaluations of the recently introduced three-phase, two-switch, zero-voltage-switching (ZVS), power-factor-correction (PFC), discontinuous-conduction-mode (DCM) boost rectifier, named the Taipei rectifier, are presented. The performance evaluation was done on a 3-kW, 400-V-output prototype designed to operate with a line-to-line RMS input voltage from 180 V to...
Digital control is becoming more and more popular in Power Supply Unit (PSU) applications. Hardware-oriented power supply designers typically need more understanding on the optimum way to implement a digital control. This paper presents different possibilities and approaches on implementing digital control for a telecom AC-input PSU. Multiple challenges affecting the control partitioning are presented...
The introduction of photovoltaic (PV) modules in the early 1970's to energize remote telecommunication sites has provided a much needed backbone for communications in far reaching and remote areas of Australia. Whilst accurate analysis of batteries is common, little data is captured on PV modules. Where a “rule of thumb” theory is applied to assessing PV capacity there is an increased risk of critical...
