AC DC Converters

The DZ-B309 is an AC DC Converter that is specifically designed to work with unstable power supplies. It is mainly used in applications where the power supply and devices require accuracy and reliable performance. The most common application fields for this device include industrial machinery, lighting systems, and power distribution systems.

Working Principle

The DZ-B309 offers a full-bridge rectifier to convert the AC power into DC power with an accuracy of 0.1%. The rectifier is made up of diodes and capacitors which are arranged in specific sequence. This allows the device to rectify the AC power supplied in from the mains and convert it into DC of fixed voltage. The DC voltage then gets regulated by the pulse width modulator, which is incorporated in the device.

The working of the pulse width modulator is simple. It has the ability to switch the DC load connected to it at a very high speed. It receives information from the microcontroller regarding the required power output and then selectively turns on and off transistors to obtain the desired output. It works by varying the power output by increasing or reducing the width of the ‘on’ time of the alternating waveform.

The output from the pulse width modulator is then transferred to a transformer where it gets fully rectified and filtered for the removal of any noise or harmonic distortion. The output from the transformer is then delivered to the load, where it goes through the rectifier and filter circuits for removal of any remaining noise or distortion, before getting delivered as the output source.

The versatility of the DZ-B309 allows it to be used for a wide variety of applications. It is specifically designed to work with unstable power supplies and provide reliable and accurate performance. The device is also easy to install and maintain, making it an ideal choice for industrial and commercial applications.
