The core of the inverter aging test equipment is an integrated system that combines power supply and energy feedback, load and operating condition simulation, data acquisition and monitoring, interface and switching unit for the tested product, as well as safety protection.
一,Power Supply and Energy Feedback Unit (Core Power Module)
As the energy hub of the aging test equipment, it is responsible for providing stable power supply to the tested inverter and efficiently processing and recovering the output electrical energy.
● DC power supply simulation:Provide a DC input for the tested inverter to meet the relevant testing requirements.
● Communication feedback load/grid simulation:It receives the alternating current output from the inverter and realizes efficient power feedback or internal recycling utilization. Compared with traditional resistive loads, the energy-saving rate can reach over 70%.
● Grid-connected energy feedback:Returning electrical energy to the power grid requires strict requirements for synchronization accuracy, harmonic suppression, and power factor control.
● DC bus closed-loop feedback:After converting alternating current into direct current, it is fed back to the direct current input terminal to form an internal energy circulation.
● Power grid simulation:Simulate complex conditions such as voltage fluctuations, frequency drifts, harmonic injections, voltage sags/supershocks, etc., to verify the inverter's adaptability to the power grid and its anti-interference capability.
