Title: Zejie Lv: Innovator in Power Conversion Technologies

Introduction

Zejie Lv is a prominent inventor based in Dongguan, China, known for his contributions to power conversion technologies. With a total of 3 patents, he has made significant advancements in the field, particularly in resonant converters and power factor correction circuits.

Latest Patents

One of his latest patents is a resonant converter and voltage conversion method. This invention includes a high-frequency inversion circuit, an inductor-inductor-capacitor (LLC) resonant tank network, and a hybrid rectification circuit. The LLC resonant tank network is separately coupled to both the high-frequency inversion circuit and the hybrid rectification circuit. The high-frequency inversion circuit is designed to convert a first direct current voltage into a first alternating current voltage. The LLC resonant tank network then adjusts this first alternating current voltage to obtain a second alternating current voltage.

Another notable patent is the bridgeless power factor correction (PFC) circuit. This circuit features a control module that collects current flowing through a current sampling element. When the current exceeds a first threshold, the control module activates a switch element. This design allows for zero-voltage turn-on of the switch element, enhancing the control module's signal anti-interference capability and reducing the delay requirement on the sampling control circuit.
