摘要
Abstract
Based on traditional inverter, the paper proposed a new circuit with power factor correction and soft-switch technology, which improves the power quality of grid and reduces power consumption. Power factor correction uses a dual switch PFC circuit with a new CCM model and provides a stable DC voltage source with low EMI and is suitable for high power. Behind that a zero-voltage turn-on circuit which consists of three auxiliary switches and LC resonant circuit is adopted. It is easy to control. At last, the paper verified its ability to test with inductive loads by software simulation.关键词
