Today, consumers are familiar with Inverter technology, primarily known for its ability to save energy for electrical devices. But what exactly is Inverter technology? How is this technology applied? Let's decode it through this article on Mytour Blog.
What is Inverter Technology?
Inverter technology is a frequency conversion technology, researched and developed by scientists from Japan. The operating principle of this technology mainly relies on advanced circuit boards, which can convert direct current into alternating current, thereby enabling electronic devices to control operating power, reduce energy consumption, aiming to save 20 – 40% of electricity consumption compared to conventional devices.
Inverter technology, renowned for its exceptional energy-saving efficiency, is now widely known and utilized in refrigeration electrical appliances. It can be regarded as one of the foremost factors consumers consider before making a purchase decision.

Explaining the operating principle of Inverter technology is relatively simple, it can be understood in the following two stages:
- Stage 1: The operation of the inverter machine is to filter single-phase or three-phase power that has been rectified in advance, converting it into flat DC power. Thanks to capacitors and a rectifier diode module, during this conversion stage, the power factor (Cosphi) of the inverter system must always be kept above 0.96, and it is also independent of the load.
- Stage 2: Through the IGBT system (Insulated Gate Bipolar Transistor), this DC voltage is converted into symmetrical three-phase AC voltage. This stage is currently implemented through Pulse Width Modulation (PWM) techniques.

This brings outstanding energy-saving efficiency and reduces losses on the motor iron core, ensuring durable motor operation. Additionally, the effects of this technology also contribute to smooth and quiet motor operation, with minimal or no noise compared to conventional products.
Advantages of Inverter Technology for Electrical Appliance Operating Power
As mentioned earlier, Inverter technology possesses the following outstanding advantages:
- Efficient energy savings for devices up to 20 – 40%.
- Maximizing operational cost reduction due to energy-saving capabilities.
- The motor always operates at low power and temperature, thereby reducing device noise and ensuring smooth operation.
- Enhancing durability and lifespan of devices by using energy sources wisely.
- Inverter-integrated products are environmentally friendly, reducing the risk of electromagnetic interference with other devices while operating simultaneously.

Comparison between Inverter and Non-Inverter
Presently, most household electrical appliances such as washing machines, refrigerators, air conditioners, etc., are equipped with Inverter technology. Below is a comparison between two product lines: Inverter and Non-Inverter.
Similarities:
Differences:
| Đặc điểm | Inverter | Non – Inverter |
| Cách thức vận hành: | Sử dụng công nghệ biến tần, giúp động cơ hoạt động chậm lại khi đạt tới nhiệt độ cài đặt.Ví dụ: Khi đạt nhiệt độ cài đặt, động cơ hoạt động chậm dần mà không tắt hoàn toàn. | Hoạt động theo nguyên lý tắt – mở, sử dụng rơ-le để cảm nhận nhiệt độ.Ví dụ, nếu nhiệt độ phòng đạt tới mức như cài đặt thì máy lạnh sẽ tự động ngắt động cơ. |
| Khả năng ổn định nhiệt độ: | Sử dụng cảm biến điện từ giúp thiết bị luôn duy trì được nền nhiệt độ ổn định. | Máy nén luôn hoạt động hết công suất nên nhiệt độ động cơ dễ nóng lên khi vận hành nhiều giờ liên tục. |
| Tiết kiệm điện năng tiêu thụ: | Thiết bị có khả năng tiết kiệm điện đến 20 – 40%. | Không tiết kiệm điện, động cơ hoạt động với công suất cao phải tiêu tốn nhiều điện năng. |
| Sửa chữa, bảo dưỡng: | Cấu tạo phức tạp nên không dễ dàng tự sửa chữa, chỉ thay thế được bằng các linh kiện chính hãng. | Cấu tạo đơn giản, dễ dàng sửa chữa hơn khi gặp hư hỏng. Đồng thời, linh kiện thiết bị dễ dàng thay thế, có thể sử dụng của nhiều hãng khác nhau nếu thích hợp. |
| Giá thành sản phẩm: | Giá thành sản phẩm cao do lợi thế tiết kiệm điện khi sử dụng lâu dài. | Giá thành rẻ. |

Common Applications of Inverter Technology
What is Inverter Technology for Washing Machines?
Washing machines equipped with Inverter technology control the motor through a processor, allowing users to actively control the rotation speed and water level through settings on the device. Moreover, Inverter technology ensures smooth motor operation, reduces noise, saves electricity, and conserves water. Thus, it prevents damaging clothes during washing cycles.

Induction cooktops with integrated Inverter technology operate the power circuit at the lowest level throughout the cooking process, utilizing maximum heat efficiency. When the temperature reaches the set level, the device automatically compresses the temperature to maintain it at the appropriate level instead of automatically turning the motor on and off like conventional induction cooktops. This significantly reduces electricity consumption for startup losses.
According to actual statistics, induction cooktops with Inverter technology can save about 15 – 20% of electricity, with premium models even reaching up to 40% electricity savings compared to conventional cooktops.
Moreover, this Inverter technology also enhances product lifespan, making induction cooktops with Inverter twice as durable as those without it.

Inverter refrigerators can save up to 40% electricity compared to conventional refrigerators. Thanks to the inverter technology that automatically compresses the motor when the refrigerator temperature reaches the desired level and maintains that temperature without automatically turning off the motor, minimizing startup losses.
An Inverter refrigerator can control different temperatures between the freezer and the fridge compartments, thereby helping food stay preserved longer and fresher.

Air conditioners with integrated Inverter technology have many superior advantages over conventional ones. In addition to maximum electricity savings, Inverter air conditioners automatically maintain room temperature at a stable level, with temperature deviation from the set level as low as only 0.5 – 1 degree Celsius to avoid disrupting sleep and causing significant temperature changes.
Moreover, the airflow from Inverter air conditioners is cooler and more comfortable than conventional ones, protecting the health of users and minimizing respiratory diseases, especially in children and the elderly.
