AC/DC converters refer to power supplies that convert from AC to DC, and they are widely used in industries, such as computers, telecommunications, automotive electrical system, military industry, and medical instruments. ZWS150BAF-3/R is one type of AC/DC converters, and it is widely used in small and medium power applications.

The ZWS150BAF-3/R converter adopts the advanced full-bridge PWM control technology and powerful microprocessor to provide constant current and voltage output and quick response. It has excellent features of high efficiency, compact design, wide input voltage range and low ripple. With high capacity and reliable performance, it is highly protected and meets all requirements of EMC.

Application field: ZWS150BAF-3/R converter is suitable for constant voltage and current power supply design, which can be used in communication base station, small and medium power industrial automation, medical instrumentation and scientific research project, etc.

Working principle: ZWS150BAF-3/R converter can provide both constant voltage and current outputs. The PWM control technology employed by the converter is based on an advanced trapezoidal pulse-width modulation method which uses a dedicated digital core control technology. The circuit is composed of an input power unit, an output rectification unit, a conversion unit, a control unit, and an output current current-limiting protective circuit.

1) Input power unit: It consists of rectification unit and power factor correction technology. The rectification unit is used to rectify and filter the AC input voltage. The power factor correction technology provides the current in phase with the input voltage, and the active power is maximized, thus improving the power factor.

2) Output rectification unit: It is composed of a full-bridge rectifying circuit. It is a key component in the output of the ZWS150BAF-3/R converter. The full-bridge rectifying circuit has a high conversion efficiency and quick response.

3) Converting Unit: The main component of the conversion unit is a power switch. When the power switch is turned on, the circuit allows the AC voltage to pass to the DC conversion. When the power switch is off, the circuit prevents the AC voltage from passing to the DC conversion. The switch is shut off and on by the control unit according to the given control signal.

4) Control unit: It is the core of the ZWS150BAF-3/R Converter. It is composed of a microprocessor and an analog circuit to ensure precise control of the voltage and current output.

5) Output current limiting protective circuit: This circuit uses a photocoupler which is connected in series with the output transformer to form a current feedback loop. It is responsible for detecting and limiting the current output and can provide overload protection and short circuit protection.

The ZWS150BAF-3/R AC/DC converter is an ideal choice for a variety of small and medium power applications. It has excellent features of high efficiency, compact design, wide input voltage range and low ripple. With high capacity and reliable performance, it meets all requirements of EMC.
