The JWS755/RA are AC to DC converters which are commonly used in many domestic and industrial applications. The basic functionality of the JWS755/RA is relatively simple, in principle converting an alternating current (AC) input to a direct current (DC) output. Generally speaking, the AC input is converted into a DC output, allowing for easier and more efficient use of electrical devices.

The JWS755/RA are AC to DC converters which are commonly used in many domestic and industrial applications. Generally, the AC input is known as the “primary voltage”, and the DC output is defined as the “secondary voltage”. This AC to DC conversion is performed by varying the duty cycle of the switches within the converter (as seen in Figure 1). Therefore, the output voltage of a JWS755/RA converter is dependent on the duty cycle of the switches.

A JWS755/RA converter consists of two primary components – a rectifier and an inverter. The rectifier (shown in Figure 2) is responsible for converting the AC input into a DC output. This is achieved by allowing either positive or negative current to pass through the diodes providing an unidirectional current every half-cycle. The subsequent DC output is then smoothed out via a filter.

The inverter (shown in Figure 3) is responsible for converting the DC output into an AC output. This is achieved by passing the DC current through the transistor switches in either a positive or negative direction and then smoothing the resultant AC output. There are also various methods available for controlling the frequency of the AC output.

In summary, the JWS755/RA AC to DC converters are used in a variety of domestic and industrial applications due to their simple design and efficient conversion of AC to DC. They allow for flexible control of both the input and output voltage and are also relatively cost-effective when compared to other AC to DC conversion options. As a result, they have gained widespread popularity in the industrial and consumer electronics markets.
