Abstract:
(EN) A PFC and LLC resonance-based intelligent full-bridge sine-wave voltage conversion circuit, comprising: an input rectification unit (10), a filtering unit (20), a PFC voltage boosting unit (30), and an LLC isolation converter unit (40), a DC voltage filtering unit (50), and an inverter unit (70). The LLC isolation converter unit comprises a first switching transistor (Q6), a second switching transistor (Q7), a first freewheeling diode (D6), a second freewheeling diode (D5), a transformer (T1), a resonant capacitor (C4), and a discharge resistor (R2B). The inverter unit comprises an inverter bridge consisting of a fourth switching transistor (Q1), a fifth switching transistor (Q2), a sixth switching transistor (Q3), and a seventh switching transistor (Q4) and a filtering inductor (L3), the output end of the inverter bridge being connected to the front end of the filtering inductor, the back end of the filtering inductor being connected to a load, and the filtering inductor being used for filtering out a high-frequency pulse in alternating current and supplying power frequency sine-wave alternating current to the load. The voltage conversion circuit can improve a power factor value and can also filter out a high-frequency pulse at an output side, so as to provide high-quality power frequency sine-wave alternating current for a load.
