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.
