AC DC Converters

The KPSA103R3 is an AC-DC (alternating current-direct current) converter module that is widely used in many fields to convert AC voltage to DC voltage. It is widely used in automobiles, chargers, UPS, solar systems, electronic meters, communications, and other power-supply equipment. It has a variety of input and output voltage ranges, and a wide input frequency range.The KPSA103R3 is a boost-flyback dual-mode converter module that efficiently captures and stores energy. It mainly consists of an active switch, a transformer, an inductor, a diode, and the passive components. The module uses a single-stage Boost-Flyback topology to boost high voltage from a low input voltage and store it temporarily in the flyback transformer. The transformer transfers the stored energy to the output capacitor to produce a stable DC voltage.The module\'s input voltage range is from 3V to 40V, with configurable output voltage ranges from 3.3V to 48V. The maximum output voltage accuracy is 0.5%, and the output voltage ripple is less than 30mV. The input frequency range is between 50Hz and 200Hz, and the module is capable of working continuously at a working temperature of -40°C to 125°C.The module has a wide range of protections, including voltage protection, current protection, over temperature protection, and short circuit protection. This ensures the safe operation of the module even under abnormal conditions or heavy load. The module has a dielectric strength of 4KV and a built-in frequency compensation circuit. This helps make the module highly efficient and stable. The KPSA103R3 also has numerous features such as high efficiency, fast response, low heat generation, and easy control.The KPSA103R3 is widely used in a variety of applications. It can be used to power devices such as LED lights, mobile phones, cameras, and industrial control systems. It is also used in solar systems and UPS for charging batteries and powering devices.In summary, the KPSA103R3 is a high power, high efficiency, stable, and reliable AC-DC converter module of the Boost-Flyback type. With its wide input and output voltage range, and a variety of protections, the module is well-suited for a variety of applications requiring a reliable and stable power supply.
