EMC techniques especially for decreasing higher harmonics in Household Electric Appliances and Wide Use Electric Apparatus are investigated and discussed. Following results are obtained by this project.1. Characteristics of PFC converter which have been developed by other researchers are investigated and summarized. As a result, one-stage converters are derived from two-stage converter by combining two semiconductor switches into one common switch to decrease electric parts. However, power losses in the PFC converter are increased due to the increase of current stress. In order to overcome this problem Hybrid-Parallel PFC converter where two different types of converters are connected in parallel is proposed. By using this converter, high-efficiency and high power-factor are achieved by adjusting the power between two converters. Small output voltage ripple can be derived by controlling the duty ratio.2.Characteristics of parallel-module PFC converter system with current-sharing controllers are discussed. Averaged current-sharing control which are widely used in a paralleled DC/DC converter system are applied to the PFC converter. As a result, stable current-sharing control and fast response are archived by adding the current-sharing signal to current reference in conventional current-programmed mode PFC converter. No degradation of power factor is occurred by adjusting the response of voltage feedback loop.

研究和讨论了专门用于减少家用电器和广泛使用的电气设备中的高次谐波的 EMC 技术。本课题取得了以下成果： 1．对其他研究人员开发的 PFC 转换器的特性进行了研究和总结。因此，一级变换器是在两级变换器的基础上，将两个半导体开关组合成一个公共开关，以减少电气部件。然而，PFC转换器中的功率损耗由于电流应力的增加而增加。为了克服这个问题，提出了混合并联 PFC 转换器，其中两种不同类型的转换器并联连接。通过使用该转换器，通过调节两个转换器之间的功率来实现高效率和高功率因数。通过控制占空比可以得到较小的输出电压纹波。2.讨论了均流控制器并联模块PFC变换器系统的特点。 PFC 变换器采用并联 DC/DC 变换器系统中广泛使用的平均均流控制。因此，通过将均流信号添加到传统电流编程模式 PFC 转换器中的电流基准，可以实现稳定的均流控制和快速响应。通过调整电压反馈环路的响应，不会出现功率因数下降的情况。
