This study presents a design enhancement of power supply system for brushless DC (BLDC) motor-driven circuits with state-of-charge (SOC) equalization and capacity expansion. The proposed design incorporates different types of battery as the input power, in which SOC equalization and battery modularization are both concerned.

This paper proposes data transmission method between primary and secondary of the flyback converter without additional communication circuit while simultaneously transferring power. In some application such as a battery charger, the data exchanges between the primary and secondary sides are necessary.

Wide-bandgap devices have been widely used to reduce the size and increase the efficiency of power converters by operating at high switching frequency, at the expense of heightened radiated and conducted electromagnetic inference (EMI) emissions, of which the latter circulate through the power loop and ancillary circuitry.

Parallel-form switch-linear hybrid (SLH) envelope tracking (ET) power supply is constituted by a linear amplifier and a switched-mode converter connected in parallel. The switched-mode converter is usually implemented by a buck converter with hysteresis current control.

One of the most critical attributes of low dropout regulators (LDOs) in increasingly complex systems on chip (SoCs) is high-power supply rejection ratio (PSRR), not only over a wide frequency range but also over a large load current range. This paper presents an LDO, realized in 65-nm CMOS, featuring >۶۰-dB PSRR over a 10-MHz frequency range and a 100-mA large load current range.

This paper presents a study of the losses in the integrated buck-flyback converter (IBFC) used as highpower-factor LED driver. The aim of the study is to investigate the possibilities of increasing the efficiency of the IBFC converter. The procedure of the improvement is done by obtaining the equations of the current through each component in terms of converter parameters.
