Description

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.
