At the Silicon Carbide 2026 (SiC 2026) conference, Hu Mao, Product Line Manager of Wuxi Silicon Power Micro-electronics Co., Ltd., took the stage to present a keynote titled "Pioneering the Fast-Charge Revolution: Si-Power’s SiC Innovations Set the Pace in Charging Technology."
With over 20 years of expertise in green power management, Si-Power is harnessing the superior electron mobility and thermal conductivity of wide-bandgap semiconductors to shrink components and supercharge power density in fast chargers and home appliances.
Having already deployed a robust portfolio of SiC solutions—ranging from co-packaged ICs to digital-analog hybrid controllers—the company is shipping tens of millions of units to tier-1 giants like Huawei and TCL, setting new benchmarks for efficiency and affordability in power electronics.
Si-Power’s SiC lineup brings game-changing thermal resilience, high-frequency operation, and rock-solid reliability to the table. In consumer fast charging, their pioneering SP9477 series (featuring an integrated 700V/380mΩ SiC MOSFET) has been widely adopted by over 20 mainstream OEMs, delivering a stunning 94.29% efficiency at 20V output while passing brutal 20KV ESD and 4KV surge testing with zero avalanche risk.
Paired with the SP9857E digital-analog hybrid flyback controller—which leverages patented Cap-Less digital control and adaptive CCM—developers can drastically cut down bulk capacitor size. The result is a fanless 65W adapter that keeps full-load temperature rises under 91.4℃, shrinking PCBA footprints and streamlining EMI design.
Beyond mobile chargers, Si-Power is scaling up for industrial and appliance power systems, bringing their SiC tech and 6035-series single/three-phase IPM half-bridge drivers to washing machines and AC units. These high-integration, high-reliability solutions are fortifying the company's consumer stronghold while paving a fast track into industrial markets.
As Phase 2 of the EU Common Charger Directive and unified Type-C mandates reshape the laptop and adapter landscape, the market is demanding unmatched price-to-performance ratios and bulletproof reliability. Si-Power answers the call with a completely localized supply chain and rigorous quality frameworks (ISO9001, ISO26262), boasting a flawless zero-major-defect track record over 2 billion chips shipped. Moving forward, the company will double down on consumer tech and appliances while aggressively expanding its SiC footprint into 750V and 1200V industrial and motor-drive applications. Armed with visionary R&D and deep system-level engineering, Si-Power is accelerating the transition toward a highly efficient, compact, and intelligent power ecosystem worldwide.
