Marching towards "new energy" and "digitalization"

In terms of industry, Menpu Opto-Magnetics belongs to the optical magnetic communication component industry, which is a sub-industry of the communication industry. However, in terms of products, magnetic components can be used not only in the communication industry, but also in power supply and new energy fields.

Mingpu Optoelectronics has a strong forward-looking consciousness, attaches great importance to technological innovation, and actively expands the application areas of magnetic components. Since 2013, it has been deploying in high-end magnetic components, automotive electronics, charging piles, new energy photovoltaic power generation, energy storage and other fields.

Ma Zongjun said: "In the field of new energy vehicles, we have cooperated with leading automakers in the industry to develop magnetic components, especially OBC and BMS. This is our strength."

The International Energy Network learned that new energy vehicles are known as "big three electrics" and "small three electrics". The big three electrics are batteries, electronic controls, and motors, while the small three electrics refer to the on-board charger (OBC), on-board DC/DC converter, and high-voltage power distribution box (PDU) in the electronic control. As the core parts of the electronic control, the "small three electrics" play an important role in converting and transmitting AC and DC energy. The on-board charger (OBC) is an important electronic device that connects to the AC charging pile and converts AC power into DC power; the on-board DC/DC converter can convert the high-voltage power output of the power battery into the low voltage required by various electrical appliances; the high-voltage power distribution box is a high-voltage power distribution unit that distributes the DC power output of the battery and monitors overcurrent and overvoltage.

The "three small electrics" have three development trends: integration, multi-function, and high power. The magnetic integration technology used by Mingpu Optoelectronics responds to this new trend. Magnetic integration technology is to wind two or more discrete devices (such as transformers, inductors, etc.) on a pair of magnetic cores, which can effectively reduce the volume and weight of magnetic components, and obtain better electromagnetic compatibility effects, achieve higher power density, and improve the performance of magnetic components. Mingpu Optoelectronics' magnetic integration technology already has mature application cases, and is constantly being improved and upgraded.

In the field of new energy photovoltaic energy storage, Ma Zongjun introduced: "We cooperate with internationally renowned micro-inverter manufacturers to make magnetic components for micro-inverters. Mentech Optoelectronics is their largest supplier."

From a global perspective, the global photovoltaic micro-inverter revenue in 2022 is about 12 billion yuan, and the cost of magnetic devices accounts for about 15% of the inverter cost. The future market potential is huge. Mentech Optoelectronics' customers are the world's leading micro-inverter manufacturers. Its micro-inverters can perform energy conversion on a single solar panel and provide energy monitoring and control for a single solar panel. This system can not only maximize the total output of the solar panel system, but also expand the configuration of solar panels.

To complete this series of refined actions, the operation of magnetic components is very important. It can be said that it is the magnetic devices of Mingpu Opto-Magnetics that determine the efficiency of the micro-inverter.

In addition to micro-inverter magnetic components, Mingpu Opto-Magnetics has formed a series of product matrix including PFC inductors, common-mode inductors, power transformers, PLC transformers and plastic-encapsulated inverter inductors for photovoltaics, relying on the R&D technology and production experience accumulated in the field of magnetic components over the years. They can be used in 50VA-500KVA photovoltaic grid-connected and energy storage inverters.

Menpu Optoelectronics has always adhered to the development strategy of technology and quality first, and built a product strategy based on technology reserves and centered on cost-effective solutions, thereby accumulating high-quality customer resources. "Menpu Optoelectronics has established good cooperative relations with many leading industries in the photovoltaic energy storage industry." Ma Zongjun said.

Ma Zongjun said: Mingpu Optoelectronics is increasing its investment in the field of new energy, and its application areas include photovoltaic and energy storage products, new energy vehicles, portable mobile power supplies, charging piles, etc.
