Introduction: Welcome to the "Mass Production Plan" of China exportsemi, here we will show you the latest and hottest mass production plans of Chinese local manufacturers. If you are interested in this, feel free to contact us for more information (china.exportsemi@ehaitech.com).
In today's wave of accelerated digitalization and energy structure transformation, the demand for efficient and reliable power solutions in various industries has never been higher. Especially in emerging fields such as home energy storage, portable energy storage, and AI server, the market is experiencing explosive growth, posing unprecedented challenges to traditional power solutions. China Exportsemi recommends to you a 3.3KW bidirectional totem pole PFC digital power supply solution based on Infineon products launched by WPG Pinjia Group, which provides a powerful "booster" for the industry.
1. Product Features (Highlights)
WPG's power supply solution has many highlights and directly hits the pain points of market demand. The main control of the solution adopts Infineon's XMC1404 MCU, which is based on the ARM® Cortex-M0® processor core, with a frequency of up to 48MHz and powerful high-speed data processing capabilities. The double-loop digital control strategy of the current inner loop and the voltage outer loop can achieve a switching frequency of up to 100KHz to ensure that the power supply can still operate stably and efficiently under complex working conditions. In terms of safety performance, the solution is equipped with comprehensive protection functions such as short circuit, over-current, under-voltage, and over-voltage, which is like putting on a solid "armor" for the power supply, and the reserved UART communication interface can fully meet the diverse real-time control needs such as motor control and digital power conversion.
The main circuit design of the solution is even more ingenious, using CoolSiC™ MOSFETs IMBG65R048M1H as the totem pole PFC high-frequency switch, with CoolMos™ MOSFETs IPDQ60R010S7 as the low-frequency switch, and the 2EDS9259X series plays the driving role, such a powerful "lineup". The result is an excellent energy efficiency and reliability of the power supply. In addition, the solution is equipped with a pluggable auxiliary power module based on Infineon's QR-Flyback IC ICE5QSBG with CoolMos™ MOSFET IPN70R360P7S to provide stable and reliable power support for key modules such as MCUs, gate drivers and fans.

2. Technical specifications
The power supply solution also performs impressively in terms of technical specifications. It supports a wide range of input voltages from 110Vac to 265Vac, and can stably output 400V DC voltage, with a maximum output power of 3.3KW (under the input condition of 160Vac to 265Vac), and can achieve an output power of 1.6KW even in the input range of 110Vac to 150Vac. The switching frequency is stable at 100KHz, which ensures efficient energy conversion of the power supply. It has a peak efficiency of 98.5% (at 50% load), a power factor of more than 0.99 (at 230Vac and a load > 20%), and an iTHD (Input Total Harmonic Distortion) of less than 5 (also at 230Vac at 20% >load). The appearance size of the entire power supply solution is only 208mm×88mm×45mm, which is small and compact, which provides strong support for the miniaturization and portability of the equipment.

3. Application scenarios
With the rapid development of AI technology and the continuous transformation of the energy structure, the home energy storage system, portable energy storage device and AI Server market is ushering in their "golden age". Relevant data show that the global home energy storage system market sales have reached $8.74 billion in 2023 and are expected to soar to $49.86 billion by 2029, with a compound annual growth rate (CAGR) of 33.68%. After a round of crazy explosive growth, the portable energy storage market has now entered a stable growth track, and the market size is expected to exceed 90 billion yuan in 2027. At the same time, the continuous expansion of the AI server market has created a thirsty demand for high-power server power supplies.
