Driven by the “dual carbon” goals, photovoltaic (PV) power generation has become a major force in energy transformation. The research, development, and mass production testing of core products such as PV modules, penyongsang, and energy storage converters place stringent demands on the accuracy, kecekapan tenaga, and operational condition simulation capabilities of DC power supply equipment. Traditional DC test power supplies suffer from high energy consumption, inability to recover excess energy, and difficulty in accurately simulating the output characteristics of PV arrays, hindering the large-scale development of the PV industry. Programmable regenerative DC power supplies, with their core technological advantages, have become a core supporting equipment for PV industry testing.
The core technology of programmable regenerative DC power supplies is perfectly suited to PV testing scenarios: They employ a fully digital dual-closed-loop control architecture, combined with active PWM rectification and high-frequency isolated bidirectional DC-DC conversion technology. This allows for accurate simulation of the DC output characteristics of outdoor PV panels under different light and temperature conditions, achieving a voltage accuracy of ±0.01%. This perfectly meets the core testing requirements of PV products, such as MPPT tracking, full-load operation, and tolerance to abnormal operating conditions. Sementara itu, the equipment supports energy feedback, efficiently feeding excess electrical energy absorbed during testing back to the grid with a recovery rate exceeding 94%. This eliminates the traditional resistance-based heating energy consumption mode, significantly reducing energy consumption and heat dissipation costs in photovoltaic production line testing.
In practical applications within the photovoltaic industry, this power supply can be widely used in photovoltaic module R&D and debugging, inverter type testing, and energy storage converter production line quality inspection. It can simulate complex operating conditions such as voltage transients and power fluctuations in photovoltaic arrays to verify product reliability. Tambahan pula, its modular design adapts to different power testing needs, simplifying the testing system architecture and improving batch testing efficiency.
