STNRGPF01

STNRGPF01 is a digital controller designed specifically for interleaved PFC boost topologies and intended for use in high power applications. The controller is capable of driving up to 3 interleaved channels, generating the proper signals in each condition. Moreover, it implements a flexible phase shedding strategy that enables the correct number of PFC channels based on the actual load condition. With this function, the STNRGPF01 is always able to guarantee the highest power efficiency across a wide range of load current requirements. The device works in CCM at fixed frequency with average current mode control, and implements mixed signal (analogue/digital) control. The inner current loop is performed by hardware, ensuring cycle-by-cycle regulation. The outer voltage loop is performed by a digital PI controller with fast dynamic response. Suitable for welding, industrial motors, UPS, battery chargers, power supplies, air conditioners.
