AI Technical Summary
Existing DC-DC power converters are difficult to design under wide gain range conditions, making it hard to improve conversion efficiency. Two-stage power conversion circuits have low efficiency and insufficient power density.
A power conversion device and method are adopted, in which the power conversion module is controlled by the control module according to the input voltage and the output voltage. The voltage conversion with a wide gain range is achieved by using the primary-side switching circuit, the resonant circuit and the secondary-side switching circuit. The method includes phase angle control, comparator module, compensation module and frequency control to improve conversion efficiency.
It achieves effective control over a wide gain range between input and output voltages, thereby improving the efficiency of power conversion.
