Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gallium nitride power supply, in particular to an interleaved parallel power supply based on gallium nitride material. BACKGROUND

[0002] The gallium nitride power supply is a power supply device taking gallium nitride, a new type of wide band gap semiconductor material, as a core element. Compared with traditional silicon-based power supplies, gallium nitride has high electron mobility, and electrons can move faster, greatly improving the efficiency of the power supply and realizing efficient energy conversion. Its resistance is low, which can reduce the conduction loss and reduce energy waste. With these characteristics, the gallium nitride power supply has many advantages: it can achieve high power density, output high power in a small size, help equipment miniaturization and portability, and the volume of some gallium nitride chargers is only 50% of the same power silicon-based power supply. Fast switching speed and short response time make it suitable for fields with high requirements for high-frequency response, such as wireless communication and radar. It is stable and reliable in high-temperature environments and can be used in electric vehicles, aerospace and other high-temperature working scenarios.

[0003] On this basis, some researchers solve the problems of current sharing control, driving signal synchronization accuracy and dynamic voltage sharing through interleaved parallel topology circuits.

[0004] Although the gallium nitride power supply has high efficiency, it still generates some switching losses and conduction losses under high-frequency working conditions. These losses will be converted into heat. The interleaved parallel power supply contains multiple power devices and inductors and other components, and the device density is high. Under high efficiency, heat is easily accumulated in a local area, causing the temperature of the device to rise. High temperature can affect the electrical performance of the device and reduce its reliability. Long-term work in a high-temperature environment can also accelerate the aging of the device and shorten the service life of the power supply. Therefore, we propose an interleaved parallel power supply based on gallium nitride material. SUMMARY
