| 摘 要： | 针对传统的交直流变换电路存在功率因数较低、易产生电网污染等问题,设计了一种以Boost电路为主电路、以MSP430单片机为微处理器的新型的单相交直流变换电路.该设计采集电压、电流信号,通过MSP430执行双闭环运算,采用有源功率因数校正技术产生PWM波,控制变换电路中MOSFET管的通断,同时实现交流侧功率因数校正.测试数据表明,该系统电路设计能够输出36 V的稳定电压,负载调整率最低可达到0.334%,功率因数调整可达到0.96以上,可满足性能指标要求,且具有较高的控制精度.

| Abstract: | Aiming at the low power factor and the pollution of power grid of conventional AC/DC converter, a Boost circuit,of which AC/DC converter was based on MSP430 was designed.The design,adopting moni-tors voltage and current signal,through the implementation of double closed loop operation MSP430,using the active power factor correction （APFC）technology to produce PWM wave,controlled on-off conversion circuit MOSFET,and at the same time realized the active power factor correction.The test data showed that this conversion circuit could output the stability voltage of 36 V.Load adjustment rate could reach 0.334%,the lowest power factor adjustment could reach above 0.96.It could meet the requirements of the performance index and had higher control precision. |
