STEVAL-ISA147V3, Evaluation Board for 500-W fully digital AC-DC power supply (D-SMPS) based on STM32F334C8 MCU
Thiết kế tham khảo bởi: STMicroelectronics
STEVAL-ISA147V3, Evaluation Board is a digital switch mode AC-DC converter consisting of two power stages: an input semi-bridgeless power factor corrector (SBPFC) controlled by an STM32F051K8 and a regulation stage implemented with an LLC half bridge with synchronous rectification (SR), controlled by an STM32F334C8 microcontroller. This 500 W AC-DC converter uses the so-called bridgeless PFC topology, with the advantage of lower conduction losses and higher efficiency by eliminating the need for a diode rectifier stage. This choice also allows a reduced component count compared to a standard PFC
