A flyback converter includes a primary-side switch connected to a primary-side winding of a transformer and a secondary-side switch connected to a secondary-side winding of the transformer. The flyback converter is operated by controlling the primary-side switch to store energy in the transformer...
This paper proposes a new approach for single-input multiple-output flyback converters operating in DCM and CCM by a small-signal averaged model. The averaged model is derived by presenting the piecewise-linear waveform for the inductor currents inside the converter. In DCM, the magnetizing ...
The single-stage flyback power factor correction (PFC) converter is well applied in medium and low power occasion such as adapters or LED drivers. Usually, the flyback PFC converter is preferred to operating in boundary conduction mode (BCM) for achieving high power factor (PF) and high effic...
With a flyback converter as an example, given input voltage: 90V to 360V, load current: 0-3A, and output voltage as 12V. The circuit parameters are as below: LP= 1.1mH, NP/NS= n = 7.7, CO= 1360μF, RESR= 30 mΩ, RS= 0.56Ω, fS= 65kHz, Se= 3.46 x 104 V/sec, GFB= ...
This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. How
Digital control method for improving light-load efficiency of asymmetrical half-bridge flyback converter[J]. Microelectronics & Computer,2023,40(9):106-113. DOI: 10.19304/J.ISSN1000-7180.2022.0731 Citation: LONG B G,WANG J F,WANG K,et al. Digital control method for improving light-load ...
The voltage and current of the PV module is fed as input to the ANN controller which generates the signals for PWM modulator. The modulator operates the two switches at the desired duty ratio for maximum power point. The proposed flyback converter can allow power transfer in both directions ...

operation during medium and low load operation and maximum power control allows limiting the input power to a level programmable by the user to increase converter safety. Abnormal conditions like open circuit, output short-circuit, input overvoltage or undervoltage, external protection circuitries and ...
The implementation of an ultra-low power DDC, characterized by an idle current in the range of hundreds of nanoamperes (nA) becomes crucial for minimizing the energy consumption of IoT devices and extending their battery life [5]. It is imperative that the converter exhibits a swift and ...
