This paper presents a flow distribution control algorithm for a tandem pump and an electric motor in an electric excavator system. Efficiency is the main issue for electric excavators since the main energy comes from the battery unlike the conventional hydraulic excavators. Better efficiency and longer working hours can be achieved if the main motor operates where the integrated efficiency of the...
A constant on-time (COT) single-inductor bipolar multiple-output (SIBMO) on-chip boost converter is proposed for LCD drivers in this study. The converter is designed for biasing some analog and digital circuits fabricated on glass substrates for benefits of extending the life of LCD. These circuits on glass require bipolar high voltages for drive LCDs. The converter boosts the input of 2.8V to two...
