The JWT75522/RA application field and working principle is one of the many AC-DC converters used to convert Alternating Current (AC) power sources into a Direct Current (DC) power source. This type of AC-DC converter is often used in industrial and commercial applications, like motor drives, lighting, and power supply control.

The JWT75522/RA is a single-stage non-isolated AC-DC converter that utilizes pulse-width modulation (PWM) control. The device employs a single-phase full-bridge rectifier, followed by an LC filter and a buck regulator. This AC-DC converter provides regulated output voltage, regardless of the input voltage ripple or load fluctuation. It also ensures reliability, efficiency, and high-power density operation.

The converter includes many features that contribute to its easy operation. For instance, an internal bypass transistor is included which helps in starting of the load and helps to reduce the inrush current. This helps to preserve the reliability of the system and reduce the headroom voltage requirements from the supply. It also comes with in-built over-current protection with auto recovery when the current returns to its normal operating levels. The converter also supports input flexibility for wide input voltage ranges.

The function of the JWT75522/RA is relatively simple. It takes the input AC voltage and converts it into DC voltage by passing it through a full-bridge rectifier. This rectifier helps to reduce the voltage ripple and helps to reduce the AC waveform into a straight line of DC voltage. After the rectification, the output is then regulated by a buck regulator to a desired voltage level. The converter’s pulse-width modulation (PWM) control ensures regulated output voltage regardless of the input voltage ripple or load fluctuation. This helps to reduce any potential damage or disruption to the system due to voltage fluctuations.

The JWT75522/RA has a wide range of uses. It can be used to power lighting systems, to supply power for motor drives, and other industrial or commercial applications. It is also efficient and reliable, thanks to its internal bypass transistor, in-built over-current protection, and input flexibility. This makes it a great choice for many applications that require a reliable and efficient AC-DC converter.
