At first glance, the power amplifier looks like three large black cabinets. 

"Don't underestimate it. This is currently the best-performing switched SiC (Silicon Carbide) quadrant power amplifier with the highest power level and power density in China. It consists of power cabinets, amplifier cabinets, and soft-start cabinets, and is the most critical equipment for power hardware in environmental simulation," said Li Jun, the manager of the R&D Management Department of Ponovo Power. 

the power amplifier acts like a special controllable power source, simulating real grid operating conditions such as microgrids, grid anomalies, and grid harmonics and meeting the needs of industries such as active distribution networks, electric vehicles, energy storage, aviation, and rail transportation in power hardware environmental simulation and testing.

Facing the blank market of high-end detection equipment, Ponovo Power overcame challenges such as high switching frequency, low power consumption, overload resistance, and software control over a period of two years. 

Finally, this January, they successfully developed this product, which has a maximum power of 120 kW, allowing users in industries such as active distribution networks and electric vehicles to detect product defects and identify performance boundaries through abnormal fault injection before the official deployment of the product. 

At the end of this November, the PAS120 Switched SiC High-Performance Quadrant Power Amplifier completed factory acceptance at an international customer's facility and began to enter the overseas market.

"To complete on-site delivery, based on the new requirements put forward by the other party in control software, protocol interfaces, etc., we coordinated the power, software, digital, structural, and production departments in less than half a month to complete all rectifications and carry out factory testing and shipment," added Li. 

In the future, focusing on the intelligent detection field, Ponovo Power will continue to inject new impetus into the industry's development through independent innovation, helping China achieve high-level technological self-reliance and accelerating formation of new productive forces.
