Switching Power Supply

Leading Power Electronics company has a complete set of DC switching power supplies required by the country’s industry in a wide range of power applications, using different structures from the power and control perspective, using soft switching techniques to reduce losses, reduce electromagnetic interference and increase the power density. These structures exhibit a variety of mechanical appearance, including die-cast plates in resin cases, standard racks, industrial boards, portable structures and custom modes for applications with limited space. Today, the use of switching power supplies with DC output is expanding with telecommunication, electric vehicles, medical equipment, oil and gas industries, power plants, the chemical industry, steel industry, aviation, marine and land industries, instrumentation laboratories and all kinds of industrial tester. The control structure of the above resources can be closed loop in a constant voltage or constant current mode so that changes in load and input voltage and other parameters of the converter in the output domain will not change. Leading Power Electronics company’s DC switching power supply has a multi-watt up to a few kilowatts and has a robust structure for long-term operation and reliable operation against severe noise, humidity and noise related issues and EMI. Including case applications, DC power supplies are used in office, industrial and telecommunication chargers, voltage regulators, LED drivers, DC motor drivers, Data Center centers, and more. According to the customer’s requirements, it can be customized to design the desired structure in terms of electrical and mechanical characteristics with the ability to program the output for a particular waveform.
