Abstract: A modularized active power filter includes a control module and at least one power module. The control module automatically identifies the number of parallel connected power modules and generates one set of PWM signals to correspondingly control the parallel connected power modules, so as to provide a final compensation current by a single power module or by plural power modules. Thereby, the compensation demand of a load is met. Consequently, the modularized active power filter is able to improve flexibility of compensation capacity, to shorten the time for service, to be suitable for mass production, and to lower the manufacturing cost.

Abstract: A DC/DC boost converter is consisted of an inductor, a power electronic switch, a control circuit, a first diode, a second diode and a capacitor. The power electronic switch is not operated if the input DC voltage is higher than the specified low reference DC voltage and it is regarded as the normal input DC voltage. If the input DC voltage is lower than the specified low reference DC voltage and this condition is regarded as the abnormal input DC voltage, the power electronic switch is controlled by pulse width modulation control and a dc voltage across the capacitor is created. Then, the output DC voltage is the summation of the input DC voltage and the capacitor voltage. Thus, the inventive DC/DC boost converter operates only when the input DC voltage is abnormal, thereby avoid additional power loss in the duration of normal input DC voltage.
