DC-DC converters are indispensable power components for modern electrical systems. TEL 8-4822WI converter is a product series developed by Tata Hitachi based on the latest converter technology. It offers fast and reliable switching rate with adjustable output voltage settings.

The application field of TEL 8-4822WI is the conversion of dc voltage. It is used for buck and boost applications, as well as battery charger and electric vehicle power supply applications. It has an average efficiency over 95% and can be used in a wide range of commercial, industrial, military and aerospace applications. With its high output accuracy and stability, it is wellsuited for controlling system voltage and providing lithium-ion battery charger.

The working principle of TEL 8-4822WI is based on switch-mode power conversion. In this converter, the voltage is shifted from a high input voltage to a lower output voltage with high efficiency. The output voltage can be controlled by the duty cycle of the semiconductor switches to adjust the output voltage and the pulse width modulation (PWM) mode of the control circuit. The main components consist of an input filter, an output filter,current limit protection, short circuit protection, oscillator, freewheeling diode, power stages and primary control IC.

Furthermore, the product series is equipped with various features to ensure reliable usage. These include EMC Filter, remote ON/OFF control, OVP, thermal shutdown, short circuit protection, protective isolation and output current control. These features allow the product easily to meet the toughest safety standard requirements.

The TEL 8-4822WI converter is designed to be very efficient in delivering high output voltage without any heat generation. It has wide input voltage range, fast transient response, less switching noise and remote On/Off control capability. Its high power density and design flexibility gives system designers more design freedom. It also has an optional external temperature sensor to ensure the safe operation of the converter even under high temperature conditions.

In summary, TEL 8-4822WI converter is an advanced power supply solution with adjustable output voltage, high efficiency and outstanding features. It provides all the essential features to make sure a reliable and safe operation. Its compact size allows designers to create small, yet powerful and efficient power supplies for a wide range of applications.
