| Abstract |
This study experimentally derives various power and current components at coordinates from instantaneous power theory applied to voltage-type nonlinear loads. An induction motor drive system is used as a voltage-type nonlinear load, and a simulated active power filter system based on DSP(Digital Signal Processor) is manufactured to verify its validity experimentally. Each power and current component of an induction motor driving 3-phase 3-wire power system is calculated with DSP to implement a simulated active power filter, and from this result, a flow of instantaneous compensation power could be experimentally verified. When various current and power components derived from instantaneous power theory are used as control reference signals of a simulated active power filter, the effect on a voltage-type nonlinear load current is experimentally investigated. |
