230V, 900W, Power Factor Regulator Conv (PFC) for Inverter Fed Drives in Appliances Reference Design (TIDA-00443)

TIDA-00443 is a 900W power factor regulator converter designed for inverter fed BLDC/PMSM motor based appliances. This reference design is a continuous conduction mode boost converter implemented using UCC28180 PFC controller and with all the necessary protections built-in. The design supports a wide AC input range from 195 VAC to 270 VAC and offers very high efficiency of >97%, over wide operating loads from 50% to 100%. The boost follower configuration utilized in TIDA-00443 aids in reducing switching losses in the PFC regulator as well as in downstream inverter/converter. This reference design delivers an efficiency of ~98%, in boost follower configuration. In comparison to fixed voltage operation, this boost follower configuration saves an additional power of 5.2 W at 230 VAC and full load. TIDA-00443 has been designed to meet the IEC-61000-2-3 iTHD limits of both Class A and Class D norms. In addition the design improves overall system performance with lower bus ripple, lower bus capacitance, lower RMS currents, and built-in front end protections. Hardware is designed and tested to pass conducted emissions, surge, and EFT as per EN55014 requirements for household appliances.

Возможности

Wide operating input range of 195 VAC to 270 VAC Designed to drive wide range of inverter fed motors and downstream DC/DC converters up to 900W. High power factor > 0.99 and less than 5% THD from medium-to-full load (50-100%). Meets Current THD regulations as per IEC 61000-3-2 Class A and Class D at both 10% and 100% load. High efficiency of > 97% at full load over entire operating voltage range and thus eliminates need for external cooling up to 55oC ambient operation. Built-in Boost follower output option provides improved efficiency (~98%). It aids in efficiency improvement of down-stream inverter and in effective reduction of DC Bus capacitance as compared to conventional solution with variable AC input. Meets the requirements of Conducted Emissions standard – EN55011 class A, EFT norm IEC6000-4-4, and Surge norm IEC61000-4-5.
