碩士 === 中原大學 === 電機工程研究所 === 104 === The rectification mechanism of the conventional diode produces a severe current distortion to the input port which results in an unwanted injection harmonics into the power grid. However, there are some limits on the amount of harmonic injection for all equipment to the power grid. For example, the standard of the International Electro-technical Commission IEC 61000-3-2 confines the input current has to be less than 16A , whereas the standard IEC 1000-3-12 restricts the input current has to be greater than 16A. The diode rectifier has been replaced by the power quality converter which has low harmonics with high power factor performance. In this technical report, we apply the one cycle control (OCC) strategy into the circuit of the active power factor correction (PFC). The OCC scheme is a nonlinear control technology which has been used in many industrial applications. This controller has a simple structure which consists of integrators, flip-flops, comparators and so on. The topology of the power factor correction has used the boost type, whereas simulations are utilized the software SIMPLIS. Base on simulation results, an analog controlled prototype for the three-phase III boost PFC has been developed and tested in a power of 9kW and a DC bus voltage of 800V, whose control IC is the IR1150 device and power stage consists of three single-phase PFC converters. Furthermore, experiments are executed as well. Satisfactory results are obtained to confirm the effectiveness and the feasibility of our theoretical analyses and design considerations.
