The new 50 W devices are designed to maximize efficiency for onboard spacecraft applications requiring long mission life up to 15 years. EL SEGUNDO, Calif. — International Rectifier, a world leader in ...

Internal operating voltages in electronic devices continue to decrease, but input-source voltages don't change. As the difference between input and output voltages increases, so does the improvement ...

Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems’ low efficiency at low input voltages at dawn and sunset. Its performance was reportedly better ...

To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

As envisioned by First Solar at their Analyst Day in 2016, the MVDC plant architecture replaces DC combiner boxes with DC-DC converters that boost string voltages from 1500V DC to the range of 5kV DC ...

Over the past few years, we have run across some teams who, for the goal of attaining maximum power, chose to run without an alternator. We started thinking about that and decided to see if there were ...
