POWER TRANSFORMING APPARATUS AND AIR CONDITIONER INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17952814 titled 'POWER TRANSFORMING APPARATUS AND AIR CONDITIONER INCLUDING THE SAME
Simplified Explanation
The present disclosure is about a power transforming apparatus that reduces stress on a converter switch during a Power Factor Correction (PFC) operation. It also includes an operation method for the apparatus and an air conditioner that incorporates it.
- The power transforming apparatus determines the number of converters needed for the PFC operation based on the input power magnitude and motor speed.
- It improves efficiency by using only one converter during low-load conditions.
- The target converter channel is selected randomly or based on previous operation history, without specifying it in advance, to avoid adding stress to any one converter switch.
Potential Applications
- This technology can be applied in various power transforming systems, such as air conditioners, to improve their efficiency and reduce stress on converter switches.
Problems Solved
- The power transforming apparatus reduces stress on converter switches during PFC operations, which can prolong their lifespan and improve overall system reliability.
- By determining the number of converters based on input power and motor speed, the apparatus optimizes the PFC operation and improves efficiency.
Benefits
- Improved efficiency in power transforming systems, leading to energy savings.
- Prolonged lifespan and increased reliability of converter switches.
- Flexibility in selecting the target converter channel, without specifying it in advance, reduces stress on any one converter switch.
Original Abstract Submitted
The present disclosure discloses a power transforming apparatus capable of reducing a stress of a converter switch during a PFC operation, an operation method thereof, and an air conditioner including the same. To this end, the power transforming apparatus according to the present disclosure may determine the number of converters for performing the PFC operation based on a magnitude of input power and a speed of the motor. Furthermore, the PFC operation may be performed using only one converter when determining a low-load in order to improve efficiency. In addition, a target converter channel may be selected using a random function or determined to be changed using a previous operation history without specifying a target converter channel in advance at an initial stage of the PFC operation so as not to add a stress to any one converter switch.
