功率因数可调单相AC-DC变换电路∗
The Single-Phase AC-DC Conversion Circuit with Power Factor Adjustable
摘要
Abstract
This design is a single-phase AC-DC conversion circuit with power factor adjustable based on UCC28019A. MSP430 is selected as the control core. We adopt the high precision 24-bitΣ-ΔADC to measure the input voltage RMS,the input current RMS,the active power RMS,the power factor and some other parameters. The power-factor correction is accomplished by UCC28019A. By controlling the digital phase shift circuit to shift the phase of the current feedback signal,the power factor can be set in the range of 0.8 to 1.0. By detecting the output current and voltage,the circuit has the function of 2.5A overcurrent protection and 36V regulated output.关键词
