Flexible digital power-factor controller

25 September 2019 Power Electronics / Power Management

Combining the flexibility of digital power with the responsiveness of analog algorithms, STMicroelectronics’ STNRGPF12 dual-channel interleaved boost-PFC (power factor correction) controller is easily configured and optimised using the company’s eDesignSuite software.

Suited to applications over 600 W, the STNRGPF12 enhances efficiency and reliability in equipment as diverse as industrial motor controls, charging stations, uninterruptible power supplies, 4G and 5G base stations, welding machines, telecom switches, home appliances, and data-centre power supplies.

The chip operates in continuous-conduction mode (CCM) at fixed frequency with average-current-mode control. The best of both digital and analog worlds meets in the STNRGPF12’s inner and outer control loops. The inner current loop utilises a hardware analog Proportional-Integral (PI) compensator, while the outer voltage loop is performed by a digital PI controller with fast dynamic response. This enables the STNRGPF12 to manage cascaded control of the voltage and current loops to regulate the output voltage by acting on the total average inductor current.
