Multiple Output Flyback Converter Design
Transactions on Electrical Engineering, 2019 DC-DC converters are mainly used to provide required output voltage by suitably controlling the pulse width modulated (PWM) signal given to the gate of the fast-acting power electronics switches. The flyback converter is one such popular isolated DC-DC converter topology used to obtain regulated output voltage in low power applications.

Thermal Runaway Detection Method for Smart Electric Bicycle Charger
Engineering Reports, Volume 7, Issue 1, January 2025.The research work introduces a novel thermal runaway detection method by using a newly developed algorithm embedded in the electric bicycle charging system. First, the relationship between the internal temperature of the battery and the phase shift of the battery impedance is derived theoretically, so that the internal parameters can be represented by ...
