AbstrakEnergi terbarukan yang berkelanjutan dan tak habis-habis seperti yang didapatkan dari angin, photovoltaic, atau pasang surut air laut menarik untuk diteliti. Bagian terpenting dari sistem energi terbarukan adalah elemen penyimpanan, seperti baterai. Dibutuhkan rangkaian konverter yang dapat diatur arah aliran daya yang mengalir untuk mengisi dan menggunakan baterai. Pengaturan ini penting karena besar daya yang dialirkan dapat menyesuaikan kebutuhan beban. Penelitian ini merancang Bidirectional DC-DC Converter dengan sistem kendali arah aliran daya dengan metode proportional-integral berbasis mikrokontroler DSPIC30f4011. Pengujian dilakukan dengan referensi tegangan ±20 V pada variasi beban 39 Ω, 50 Ω, dan 100 Ω. Hasil pengujian menunjukan bahwa kontrol Proportional-Integral dapat bekerja dengan baik untuk digunakan sebagai pengendali arah aliran daya dengan cara meregulasi dan menjaga nilai tegangan DC Bus konstan sebesar 20,2 V pada beban resistor 39 Ω, 20,4 V pada beban resistor 50 Ω dan 20,4 V pada beban resistor 100 Ω. Ketika nilai daya yang dihasilkan sumber kurang dari besar daya yang dibutuhkan beban, maka terjadi discharging battery. Namun ketika hal sebaliknya terjadi, maka berubah menjadi charging battery. AbstractSustainable and endless renewable energies such as those obtained from wind, photovoltaics, or tides are interesting to study. The most important part of renewable energy systems is storage elements, such as batteries. A converter circuit that can be set in the direction of the flow of power to charge and discharge the battery is needed. This setting is important because the amount of power supplied can adjust load requirements. This Research designs a Bidirectional DC-DC Converter with a power flow direction control system with proportional-integral method based on DSPIC30f4011 microcontroller. The test was carried out with a reference voltage of ± 20 V at load variations of 39 Ω, 50 Ω, and 100 Ω. The test results show that Proportional-Integral control can work well to be used as a controller of the direction of power flow by regulating and maintaining a constant DC bus voltage of 20.2 V at a resistor load of 39 Ω, 20.4 V at a 50 Ω resistor load and 20.4 V at 100 resistor load. When the value of the power generated by the source is less than the power required by the load, discharging battery occurs. But when the opposite happens, it changes to a charging battery.

“…The converter should be characterized by: very high efficiency and minimal size, increased voltage cell and sinusoidal output voltage as well as the ability to work with parallel connections. These requirements enable the connection to modern PE converters [27][28][29][30][31] realized on the basis of currently available PE components [32][33][34]. In conventionally configured PV systems, generally of greater power, an internal DC bus is frequently used (Fig.…”

Abstract. This article gives a tutorial overview of the most important issues related to the use of power electronic systems in power engineering, with respect to the urgent need for modernization of existing grids in the direction of intelligent networks. The main problems and conditions bound up with the construction of Smart Grids and the location, as well as functioning in them of the most important power electronic systems are presented here. Special attention is directed therein to the potential possibilities of so-called 'smart' transformers and V2G and V2H technologies.

Abstract.A new concept of a DC-DC converter with galvanic isolation is proposed in this paper. The converter belongs to the class E resonant converters controlled by pulse width modulation via frequency regulation (PWM FM). Due to the possibility of operation in the boost and buck modes, the converter is characterized by a high range of voltage gain regulation. The principle of converter operation described by mathematical equations is presented. The theoretical investigations are confirmed by p-spice model simulations and the measurement of an experimental model of 1kW laboratory prototype.
