Efficient resonant power conversion

IEEE Transactions on Industrial Electronics, 1990
The DC analysis of a series-resonant converter operating above resonant frequency is presented. The results are used to analyze the current form factor and its effect on the efficiency. The selection of the switching frequency to maximize the efficiency is considered.

Repeater Power Conversion Efficiency in Submarine Optical Communication Systems

IEEE Photonics Journal, 2021
In power-limited trans-oceanic submarine systems, the electrical-to-optical (E/O) power conversion efficiency determines the amount of optical signal power generated by repeaters, which governs the cable capacity.

Improvement of the power conversion efficiency of a personal computer

2013 IEEE International Symposium on Industrial Electronics, 2013
Most low‐power PC design research focuses on the power consumption of devices in the system, in order to reduce the consumption of the peripheral components while the system is in the idle state. In this design, the power conversion efficiency of the multi‐phase pulse width modulation power regulator can be improved by using the auto‐phase switching ...
