A synchronous rectifier is an electronic device that changes alternating current (AC) electrical power into direct current (DC) electrical power. It converts AC power into DC power by using a rectifier circuit, which switches on and off in synchronization with the AC power input.
This allows the rectifier to control the conversion process, resulting in improved energy efficiency, increased power delivery, and reduced electromagnetic interference (EMI).
The synchronous rectifier works by using a rectifier circuit that contains transistors, diodes, and other components. The circuit switches on and off in synchronisation with the AC power input, and as the input waveform changes, the transistors and diodes in the circuit adjust accordingly.
This ensures that the output of the rectifier is always in phase with the input waveform, and the output current is always in the same direction regardless of the input voltage.
The synchronous rectifier is commonly used in a variety of applications, including power supplies, chargers, inverters, and DC/DC converters. It is also used in automotive and industrial applications, as well as in renewable energy systems like solar power systems and wind turbines.
The synchronous rectifier is an efficient and reliable way to convert AC power into DC power, and it is an important component of many modern electronic systems.
It helps reduce power loss and improve overall efficiency, and its ability to reduce EMI makes it a great choice for applications in which high-frequency interference must be kept to a minimum.
The Global Synchronous Rectifier market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A New MOSFET Driver for Synchronous Rectification was launched by Diodes Incorporated. The APR348 can operate in QR, CCM, and DCM flyback modes and accept secondary-side output voltages of up to 20 V. Diodes Incorporated’s APR348 is intended for use in a variety of secondary-side synchronous rectifier applications where external MOSFETs need to be driven. It can be used in implementations that are low-side or high-side.
Because of this secondary-side MOSFET driver’s high level of integration, engineers won’t need many extra parts for their designs. The 5 V to 20 V power converters found in a wide range of portable, consumer, and home automation devices are the target market for the APR348. Additionally, it will be useful for rapid charging and USB power delivery (PD) applications.
With the introduction of the JW77 series synchronous rectifier chip, a significant advancement was made possible by the integration of the synchronous rectification controller, synchronous rectification MOS tube, single SOP-8 chip, and VCC power supply capacitor.
I work with some domestic IC manufacturers that have launched the DK5V45/100 series, which is designed for synchronous rectification and doesn’t require any external current limiting resistor or VCC power supply capacitor. The Schottky diode can be directly replaced with the TO-277 package without modification.
