What Is An Inverter-integrated Transformer?

An inverter-integrated transformer is a power conversion device that integrates the functions of an inverter and transformer in one device and is widely used in renewable energy systems such as solar photovoltaic power generation and wind power generation. Its main role is to convert direct current (DC) to alternating current (AC) and boost or reduce voltage through the transformer to adapt to the requirements of the grid or load.

1. Basic function and working principle

Inverter function

DC to AC conversion: The core function of the inverter is to convert direct current from a solar panel or wind turbine into alternating current. This conversion process requires precise control to ensure the output AC has the appropriate frequency and voltage.

Power quality: The inverter-integrated transformer can provide high-quality power output, reduce harmonic distortion, and ensure stable and reliable power.

Transformer function

Voltage adjustment: The integrated transformer can adjust the inverter output AC voltage to a voltage level suitable for the transmission and distribution grid or specific application. Usually includes booster (raising low pressure to high pressure) and buck (lowering high pressure to low pressure) functions.

Isolation: The transformer provides electrical isolation, increases the safety of the system, and prevents electrical faults on the DC side and the AC side from affecting each other.

2. Application scenario

Solar photovoltaic system

Residential and commercial solar systems: Inverter-integrated transformers convert the direct current generated by solar panels into alternating current suitable for home or commercial use and adjust the voltage to match grid requirements.

Large photovoltaic power plants: In large photovoltaic power plants, inverter-integrated transformers can centrally handle the power output of multiple photovoltaic arrays, optimizing energy management and delivery.

Wind power system

Distributed wind power systems: In distributed wind power applications, inverters integrate transformers to convert direct current or low-voltage alternating current generated by wind turbines into high-voltage alternating current suitable for the grid.

Wind farms: In large wind farms, inverter-integrated transformers can centrally manage the output power of multiple wind turbines, improving system efficiency and stability.

3. Strengths

Compact design: Due to integrating inverters and transformers in one device, the number of devices and the space taken up are reduced and suitable for installation in space-limited environments, such as urban buildings and small wind farms.

High performance: The integrated design reduces losses during energy conversion and improves overall system energy efficiency.

Simplify installation and maintenance: The integrated design reduces the complexity of connection and installation while simplifying the system's maintenance and management.

Enhanced reliability: Through integrated design, the reliability of the system is improved and the points of connection failure between components are reduced.

4. Technological progress and market trends

With the continuous progress of technology, inverter-integrated transformers continue to improve in terms of efficiency, reliability, and intelligence. Modern inverter-integrated transformers usually have intelligent monitoring and management functions, can monitor the status of the system in real-time, fault diagnosis and predictive maintenance, and improve the operating efficiency and reliability of the system.
