This paper presents a hybrid control strategy for the LLC resonant converter in X-ray machines, addressing the limitations of voltage gain range under Pulse Frequency Modulation (PFM) and dynamic response under Phase Shift Modulation (PSM). The strategy employs an improved fruit fly optimization algorithm (IFOA) to optimize PI control and integrate...

It is envisioned that in the near future, a hybrid operation between DC and AC systems may be observed. Hence, this paper proposes a new DC-DC/AC flyback-based power converter with the least number of components featuring a dynamic voltage conversion ratio. This converter serves as a power electronics interface, adaptable for employment in DC, or A...

Control of a single-ended primary inductor converter (SEPIC) is a challenging task as it is a fourth-order non-linear system. In this paper, an active disturbance rejection control (ADRC) scheme is proposed for the SEPIC converter with a high switching frequency. Selection of the observers and controller bandwidth is done according to the maximum s...

This paper proposed a fully integrated adaptive on-time (AOT) controlled buck converter with fast load transient. An adaptive on-time generator is presented to stabilize the output frequency. To enhance the light load efficiency, the converter could transfer from the pulse width modulation (PWM) to pulse skip modulation (PSM) as the load current de...

This work explores the potential of piezoelectric DC-DC converters as a viable alternative to inductive-based converters. Their exceptional frequency-scale property and planar shape make them highly promising. However, for seamless integration, it is crucial to incorporate the power stage into a single chip. By utilizing the most favorable piezoele...
