Validation Aspects for Grid-Forming Converters Based on System Characteristics and Inertia Impact
Energies, 2023 Grid-forming converters are considered a key technology for electrical grids with a high share of renewable energy. However, there is a lack of a general, robust and verifiable definition of what constitutes this behaviour. Therefore, this paper presents

Sensorless multi-loop control of phase-controlled series-parallel resonant converter [PDF]
, 2014 This paper proposes a multi-loop controller for the phase-controlled series-parallel resonant converter. Output voltage is solely measured for control and inner loop is used to enhance closed loop stability and dynamic performance compared to single-loop

DSP controlled power converter [PDF]
Proceedings of 1995 International Conference on Power Electronics and Drive Systems. PEDS 95, 2002 A digital controller is designed and implemented by a digital signal processor (DSP) to replace the PWM and error amplifier compensation network in a two wheeler forward power converter. The DSP controller is designed using three approaches: (a) discretization of analog controller-the design is based on the transfer function of the error amplifier ...

The Hydraulically Controlled Oscillating Piston Converter [PDF]
Energies, 2021 One way to realize inertia in energy saving hydraulic switching converters is a mechanical oscillator connected to a piston. Its two basic advantages over the use of fluid in an inductance pipe are higher compactness and a better decoupling of inductance and capacitance; these are opposed by a more complex valve system, which raises costs if electric ...

Flyback converter controlled by Arduino Uno [PDF]
Journal of Techniques, 2020 This paper presented the design, simulation, and implantation a DC-DC step-up Flyback converter that regulates the output voltage to give the desired value 200 V 100 W and can be used in many application such as power supply. To give a regulated output voltage from the flyback converter, a feedback loop with Proportional-integral (PI) controller is ...
