TE90A1502Q01 is a power conversion product designed for AC DC Desktop, Wall Adapters applications. It provides low-cost power factor correction, while its size is up to 10 Watts. The product is designed to meet IEC61000-3-2 global harmonization standards for harmonious current to ensure a high level of compliance with EMC (electromagnetic compatibility) and safety requirements.

The working principle of TE90A1502Q01 is a combination of active and passive components. The system mainly consists of active components such as MOSFETs, IGBTs, and capacitors, and a high frequency LC type input filter. The components are connected in a series and parallel configuration to provide efficient power conversion while minimizing overall current THD.

The input power supply is fed into the power transformer, which then induces the voltage into the bridge rectifier. The rectifier converts the AC into DC, which is stored in a filter capacitance. The stored electrical energy is furtherrectified by the active components.The active components consist of power MOSFETs, IGBTs and associated gate drivers.The components are controlled by a microcontroller, which can adjust the switching parameters depending on the load and operating environment.

The output current is regulated by a Feedback Control Loop (FCL) with a sensing voltage of 20mV. The sensing voltage is fed into the Analog Front End (AFE) module, where it is kept under control. The FCL monitors the output current and adjusts the switching parameters of the active components in order to keep the output current constant. The FCL also provides overcurrent protection. Once an overcurrent condition has been detected, the microcontroller will shut down the device.

TE90A1502Q01 has a wide range of operating temperature range and is suitable for both commercial and domestic applications. The power conversion efficiency is up to 90%, meaning that waste heat is minimized. The device is also protected against short circuits, over-temperature conditions, and is compliant with RoHS and EMC standards.

TE90A1502Q01 is a reliable and cost effective AC DC Desktop, Wall Adapters product. The device is designed to ensure a high level of compliance with EMC (electromagnetic compatibility) and safety requirements, while providing effective power conversion. Its wide range of operating temperature range and excellent power conversion efficiency make it suitable for both domestic and commercial applications.
