Power Conversion Systems (PCS) are the backbone of modern electrical engineering, enabling transformation, regulation, and precise control of electric power across diverse voltage and frequency levels. Their ability to facilitate bi-directional power flow makes them indispensable in renewable energy integration and advanced energy storage solutions.

Unipar’s PCS are engineered for exceptional versatility and high performance. They are ideally suited for grid-connected applications such as photovoltaic (PV) and wind power systems, as well as Energy Storage Systems (ESS) based on lithium-ion batteries and hydrogen fuel cells (HFC). By employing advanced phase-locked loops (PLL), the PCS units synchronize efficiently with grid voltage and frequency. The incorporation of maximum power point tracking (MPPT) algorithms ensures optimal energy harvesting in renewable installations.

A standout feature of Unipar’s technology is its dual-mode IGBT Rectifier Active Front End Converter, delivering a current THD of less than 3%, thereby guaranteeing significantly cleaner power conversion. The systems further integrate advanced grid-support capabilities including voltage and fault ride-through (VRT/FRT) and robust harmonic mitigation — all powered by cutting-edge pulse-width modulation (PWM) technology.

For ESS applications, Unipar PCS support both isolated and non-isolated bi-directional conversion. The isolated mode is driven by a proprietary high-frequency conversion technology (patent pending), while the non-isolated mode leverages reliable back-to-back converters. This architecture enables seamless switching between charging (rectification) and discharging (inversion) cycles. Advanced DSP-based closed-loop control ensures superior voltage stability, frequency regulation, and overall power quality.

These PCS units are fully compatible with SCADA and Energy Management Systems (EMS) via industry-standard communication interfaces such as RS485/Modbus and CAN. Unipar emphasizes critical engineering requirements such as thermal management, electromagnetic compatibility (EMC), and fault tolerance, ensuring long-term reliability and operational safety.

At their core, Unipar’s Power Conversion Systems function as intelligent, adaptive interfaces between energy sources, storage mediums, and load centers — enabling responsive, efficient, and smart power flow for the rapidly evolving electrical grid and future-ready energy infrastructure.
