Abstract

The invention discloses a power transfer power supply circuit, which includes a voltage control circuit, an oscillation circuit, a transformer, a power output circuit and a power transfer state monitoring circuit. The input DC voltage signal is converted into an AC oscillating signal of a specific frequency. The transformer is used to isolate the front and rear stages and transmit the signals separately. After filtering and rectification, it is converted into a DC driving voltage to control the conduction of the power supply battery output circuit and the power transfer status monitoring circuit. It also discloses the operation method of the circuit, realizes the switching control of the ground power supply and the battery power supply of the system, and has functions such as combined output of two power supply lines and power transfer status monitoring. , has a high isolation voltage, and adopts redundant and current sharing design. The circuit has strong scalability, which can not only expand the current capacity, reduce power consumption, but also meet the redundant design of the circuit.

Description

technical field [0001] The invention belongs to the technical field of semiconductor integrated circuit design, and in particular relates to a power transfer circuit and an operation method thereof. Background technique [0002] The power conversion circuit is a widely used electronic product, which is used for the conversion control of the power supply. The current transfer power supply circuit has a large volume, weight, and high thickness, which is no longer suitable for the miniaturization requirements of integrated circuits, and does not meet the requirements of combining two power supply lines for output while ensuring small VDMOS on-resistance and low power consumption. . Therefore, there is an urgent need for a high-reliability transfer power supply circuit based on aluminum-based heat dissipation technology, which can realize the miniaturization design of the circuit while completing the functions of power supply, conversion power supply control, two-way power supp...
