Power Integrations offers design example report for high-efficiency 900W power supply
Power Integrations
DER-274 (for HiperPFS)
Power Integrations has published DER-274, a new design example report that describes a 900W power supply with 97 per cent efficient active power factor correction (PFC), designed for use in white goods, blowers, motor control drives and computing applications.
Based on the company’s HiperPFS family of high-efficiency PFC controller ICs, this design is claimed to offer a smaller, lighter and higher-efficiency alternative to passive PFC systems, which also reduces component count and board footprint.
