AC/DC converters are widely used in daily life, from home entertainment to industrial and commercial applications. In order to meet various applications’ needs, several kinds of AC/DC converters, including PWM, push-pull, and hybrid converters are developed. The JWT75525/RB AC/DC converter is an example of the hybrid converter, which exhibits the advantages of high speed, low cost, and low-harmonic distortion.

The working principle of the JWT75525/RB application is derived from a combination of multiple switching modes. The primary operating mode is a single-phase fully-controlled bridge rectifier with a voltage source inversion (VSI) topology. The VSI topology consists of two uncontrolled bridge rectifiers, one of which is used to boost the voltage, and the second is used to dissipate power.Thus, a rectified AC voltage, with a peak voltage more than three times that of the input voltage, is supplied to the load.The VSI topology operates by passing the input voltage through a controlled bridge rectifier, and then introducing the resulting voltage back into the AC supply line to regulate the output voltage.

Moreover, this AC/DC converter also works with several additional features, such as active rectifier, pre-regulation, and over-current protection.The active rectifier uses pulse width modulation (PWM) to protect the main power source from surges and overloads, and further maintains a stable output voltage. The pre-regulation enables the converter to maintain a precise output voltage over a wide line input. This feature could be beneficial for applications that requires high accuracy and reliability. Last, the over-current protection keeps the converter from being over-loaded or malfunctioning due to excessive current draw.

In addition, the JWT75525/RB converter has several benefits, such as higher efficiency, betterripple suppression, and low-harmonic distortion.Since it combines both hard-switched and cyclo-converter topologies, it can attain higher switching speeds than an ordinary cyclo-converter, resulting in higher overall efficiency. Moreover, since it exhibits lower output voltage ripple than other converters, it is able to provide constantvoutput voltage with minimal noise content to the load. Additionally, due to its inherent power conversion technique, it generates low-harmonic distortion and is able to meet most stringent international noise discharge standards.

Overall, the JWT75525/RB converter can be used for a range of applications.From powering small appliances to controlling large industrial equipment, it is suitable for a wide variety of applications. Its numerous advantages, such as higher efficiency, better ripple suppression, and low-harmonic distortion make it an ideal choice for many applications.
