Eskom provides 98% of South Africa’s ever increasing electricity demand. The mining sector is a vital contributor to the economy, but also consumes vast amounts of electricity. This sector is responsible for almost 15% of the country’s electricity usage. Mines heavily depend on the supply of cold water and air. Refrigeration systems are therefore constantly operational and can account for 25% of a mine’s electricity costs. The need therefore exists to investigate possible energy savings initiatives. Refrigeration systems are typically used to lower the temperature of water and air. Bulk Air Co

In the highly competitive global environment, the relatively small-scale of bulk shipping market in Taiwan makes the business operations much more difficult than other bulk shipping markets. Therefore, how to enhance shipping competitiveness by improving the operational performance is an important issue for bulk shipping corporations.

The derived circuits are obtained from the integration of a dual-switch boost-type or buck-boost-type power factor corrector (PFC) into a half-bridge resonant converter. With symmetrical topology, the circuit is simple and the voltage and current stresses on the two active power switches are identical to each other. The PFC is operated at discontinuous conduction mode (DCM) to achieve unity power factor. The re

High-frequency operation can reduce the inductor size and the converter’s volume. The inductors for the interleaved topology are integrated into one inductor. Additionally, the traces on the PCB are treated as windings to further reduce the cost and volume. With the buck-type topology, the voltage rating for the output capacitor is lower. High switching frequency will result in higher switching loss. Therefore, GaN-based FET

When input voltage is higher than output voltage, the MPPT operates in buck mode; otherwise, it operates in boost mode. When input voltage changes between high voltage and low voltage, the mechanism of changing reference input voltage is adopted to switch the operation mode. This tracker controller uses microcontroller TMS320LF2406A, and the control algorithm is based on the perturb and observe method. In add
