摘要:This paper presents a voltage frequency conversion system with Digital Signal Processor (DSP).The digital control is used to achieve the variable frequency control.The topology of the proposed system is two-stage converter,where the first stage is a power factor correction (PFC) circuit and the second stage is a single-phase full-bridge inverter circuit.The PFC can control input AC voltage,which can achieve high input power factor.Otherwise,it also can supply a regulated DC bus voltage for the full-bridge inverter.The variable output voltage frequency can be controlled in the full-bridge inverter by using the DSP.Finally,a prototype system operates frequency varied from 50 to 400Hz is designed and implemented.The experimental results validate the advantages of the proposed variable frequency control.
