Abstract
A modularized active power filter includes a control module and at least one power module. The control module automatically identifies the number of the 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 single power module or plural power modules. Thereby, the compensation demand of a load is met. Consequently, the modularized active power filter is able to improve the flexibility of compensation capacity, shorten the time for service, be suitable for mass production, and lower the manufacturing cost.
Claims9
A modularized active power filter, comprising:
- a control module;
- a control signal bus;
- and
- at least one power module, electrically connecting with the control module through the control signal bus;
- wherein the control module automatically identifies the number of the at least one power module and generates one set of PWM signals to control the at least one applied power module;
- and at least one applied power module generating a final compensating current to suppress the harmonic currents and compensate for the fundamental reactive current of a load.
