Dual Active Bridge (DAB) converters can play an important role in the development of medium and low voltage DC networks, allowing interconnections at different voltage levels. Depending on the converter topology and the control strategy of the power electronics, strong offset<\/em> currents may appear, causing saturation, increased losses and overloading of the power electronics. This study reworks a control strategy in the analog domain to avoid the generation of such offset<\/em> currents in DAB converter simulations; the method is used both for the validation of software<\/em> models and for Real-Time (RT)<\/em> tests. Software<\/em> simulations of the converter in the continuous domain were compared to the equivalent in the discrete domain to evaluate the origin of the offset DC currents,<\/em> in order to develop a digital compensation strategy. The proposed technique, also validated with Control Hardware in The Loop<\/em> (CHIL) tests in Real-Time<\/em> , was successfully implemented in the simulations. The method has been shown to compensate for offset<\/em> currents that occur in certain operating configurations. Compensation of offset<\/em> direct currents is achieved with the simple and fast integration of the control algorithm into the control schemes of existing converters, avoiding significant modifications and preserving the validity of the original model.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download Memory","link":"https:\/\/ieeexplore.ieee.org\/document\/9504673"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-07-21","autori":"A.
