Abstract ▼ AI-Helper

This paper presents a power supply for gate drivers, which uses a magnetic resonance wireless power transfer system. Unlike other methods where multiple antennas are used to supply power for the gate drivers, the proposed method uses a single antenna in an insulated receiver to make multiple mutually isolated power supplies. The power transmitted via single antenna is distributed to multiple power supplies for gate drivers through resonant capacitors connected in parallel that also block DC bias. This approach has many advantages over other methods, where each gate driver needs to be supplied with power using multiple receiver antennas. The proposed method will therefore lead to a reduction in production costs and circuit area. Because the proposed circuit uses a high resonance frequency of 6.78 MHz, it is possible to implement a transmitter and a receiver using a small-sized spiral printed-circuit-board-type antenna. This paper used a single phase-leg circuit configuration to experimentally verify the performance characteristics of the proposed method.

When compared to conventional methods in an isolated power supply configuration, the proposed method demonstrates advantages such as reduction in cost and circuit area. The proposed method was verified by conducting PCB test board experiments, and it was verified that it could effectively isolate the power supplies to drive the gates of different switches. Therefore, this paper is expected to provide advantages in the implementation of various high voltage and high power applications.
This paper describes an isolated power supply with a new structure, based on the magnetic resonance wireless power transfer method. The proposed structure is simple and provides isolated power to multiple gate drivers, using a single Rx antenna. By using a high resonance frequency of 6.
This approach will indeed reduce the cost and circuit area, but will face constraints as it will have to use multiple receiver antennas. Therefore, this paper proposes a new isolated power supply design with a magnetic resonance wireless power transfer system to supply isolated power to multiple gate drivers using a single Tx and Rx antenna.
