Perkembangan sistem pengisian baterai kendaraan listrik berbasis hybrid mendorong kebutuhan inverter yang mampu menyalurkan daya ke beban sekaligus berinteraksi dengan jaringan listrik secara terkendali. Penelitian ini membahas perancangan dan realisasi prototipe H-bridge Voltage Source Inverter (VSI) satu fasa grid-connected menggunakan Sinusoidal Pulse Width Modulation (SPWM) unipolar. Sistem dioptimasi untuk menghasilkan arus keluaran yang sefasa dengan tegangan jaringan melalui kontrol arus Proportional–Integral (PI) dan sinkronisasi Phase Locked Loop (PLL), guna memastikan penyaluran daya ke grid dan beban berlangsung secara presisi.
Metode penelitian ini menerapkan pendekatan eksperimental melalui perancangan dan implementasi prototipe inverter. Sistem kendali digital direalisasikan pada mikrokontroler Arduino Uno dengan umpan balik arus, sementara pengoperasian saklar daya didukung oleh rangkaian penggerak dan mekanisme dead-time berbasis perangkat keras untuk memastikan proses pensakelaran yang aman pada konfigurasi H-bridge.
Hasil penelitian menunjukkan bahwa pada tahap simulasi, sistem inverter mampu menghasilkan arus keluaran yang tersinkronisasi dengan jaringan secara stabil dan rendah distorsi. Namun, pada realisasi fisik, prototipe inverter H-bridge VSI berbasis SPWM unipolar belum mampu memenuhi karakteristik operasi grid-connected. Kendala utama terletak pada sinkronisasi PLL–ZCD yang belum menghasilkan penguncian fase stabil, serta sistem pengendalian arus yang belum optimal dalam menginjeksikan daya aktif ke jaringan. Akibatnya, terjadi deviasi performa yang signifikan antara prototipe dan simulasi akibat keterbatasan implementasi perangkat keras.

Abstract — The development of hybrid-based electric vehicle charging systems drives the need for inverters capable of delivering power to loads while interacting controllably with the power grid. This study discusses the design and realization of a single-phase grid-connected H-bridge Voltage Source Inverter (VSI) prototype using unipolar Sinusoidal Pulse Width Modulation (SPWM). The system is optimized to produce an output current in phase with the grid voltage through Proportional–Integral (PI) current control and Phase Locked Loop (PLL) synchronization, ensuring precise power delivery to both the grid and the load.
The research method employs an experimental approach through the design and implementation of an inverter prototype. The digital control system is implemented on an Arduino Uno microcontroller using current and voltage feedback, while the power switching operation is supported by gate driver circuitry and a hardware-based dead-time mechanism to ensure safe switching operation in the H-bridge configuration.
Research results demonstrate that in the simulation phase, the inverter system effectively produces an output current synchronized with the grid, characterized by stability and low harmonic distortion. However, in the physical implementation, the unipolar SPWM-based H-bridge VSI prototype fails to meet grid-connected operational standards. The primary constraints involve the PLL–ZCD synchronization, which lacks stable phase locking, and the current control system that is unable to optimally inject active power into the grid. Consequently, there is a significant performance deviation between the prototype and simulation due to hardware implementation limitations
