Abstract

With the increasing global commitment to renewable energy sources like photovoltaics (PV), there is a critical need for high-efficiency and high-power-quality converter topologies. Traditional two-stage PV systems are often complex and introduce significant Common Mode Voltage (CMV), leading to issues like leakage currents, high electromagnetic interference, and safety concerns. This paper proposes the Integration of a Bidirectional Cell within a quasi-Z-Source Inverter (BC-qZSI) to achieve CMV Reduction in a single-stage power conversion setup. The BC acts as an active balancing and filtering element rather than solely a boosting stage, ensuring a continuous current mode and actively suppressing the high-frequency CMV components generated by the shoot-through states. The analytical mathematical expression of the proposed topology is derived to confirm its operation, voltage boost capability, and CMV characteristics. Ideal simulation results, performed using PSIM software, validate the derived expressions and demonstrate the effectiveness of the proposed design. The topology achieves a significant reduction in CMV, lowering its amplitude more than 90% compared to the conventional qZSI. Furthermore, the output waveform quality is excellent, yielding a Total Harmonic Distortion (THDv) of 2 %, which complies with the IEEE Std 519-2014 standard for acceptable waveform quality. These results confirm that the integrated BC-qZSI topology effectively mitigates CMV while maintaining high power quality and a single-stage architecture.

Abstract

This paper proposes a speed control strategy of Synchronous Reluctance Motors (SynRM) using an Indirect Matrix Converter (IMC) combined with a finite model predictive speed control (MPSC) and PI current control. This control algoritm is chosen than fully PI in both loops due to improve overall system stability and dynamic response. The IMC architecture offers advantages such as compactness, bidirectional power flow, and the elimination of bulky passive components, making it ideal for efficient motor drive systems. The proposed control method employs predictive algorithm using augmented state variable and cost function minimization technique. In addition, PI controllers here using a pole-assignment method. Both proposed controls aim to guarantee stability and responsiveness for dynamic performances. The MATLAB/Simulink is used here to simulate the system, incorporating practical motor parameters and space vector modulation techniques. Simulation results show that the control algorithm attains satisfactory speed performance, with minimal steady-state error 0.47%, overshoot below 2%, and fast settling time under various load 0.035 seconds and speed profiles. Additionally, the system performs robustly under reversed and sinusoidal speed commands, demonstrating its effectiveness and suitability for real-world industrial applications also need to implement in the experiment for the future works.

Abstract

Pemanfaatan energi surya merupakan salah satu solusi strategis dalam meningkatkan kemandirian energi dan kualitas fasilitas umum di wilayah pedesaan. Desa Began, Kecamatan Glagah, Kabupaten Lamongan, Jawa Timur, memiliki potensi energi surya yang cukup besar, namun pemanfaatan dan pemeliharaan sistem pembangkit listrik tenaga surya (PLTS) masih menghadapi keterbatasan pengetahuan dan keterampilan masyarakat. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas masyarakat dalam penggunaan dan pemeliharaan PLTS, khususnya PLTS Penerangan Jalan Umum (PJU), melalui pelatihan dan pendampingan teknis. Metode pelaksanaan meliputi survei awal pada fasilitas desa, yaitu masjid, jalan desa, dan area pemakaman, untuk menentukan lokasi penempatan yang tepat, dilanjutkan dengan pelatihan penggunaan dan pemeliharaan PLTS yang dilengkapi dengan pretest dan posttest sebagai instrumen evaluasi. Selain itu, masyarakat dibekali dengan buku saku sebagai panduan praktis penggunaan, pemeliharaan, dan penanganan gangguan (troubleshooting). Hasil kegiatan menunjukkan adanya peningkatan pemahaman dan antusiasme masyarakat terhadap pemanfaatan energi surya, yang tercermin dari peningkatan hasil posttest serta partisipasi aktif peserta selama pelatihan. Kegiatan ini diakhiri dengan serah terima PLTS PJU dan buku saku kepada masyarakat Desa Began sebagai luaran nyata kegiatan pengabdian. Secara keseluruhan, kegiatan ini berkontribusi terhadap pencapaian SDG 7 (Energi Bersih dan Terjangkau),dan SDG 11 (Kota dan Permukiman Berkelanjutan) melalui peningkatan kemandirian energi dan kapasitas masyarakat desa.
