Abstract

abstract in a direct power converter employing a boost chopper, a peak current flowing an inductor of the boost chopper is reduced. when a rectifying duty dr, a discharge duty dc, a voltage between both ends vc of a capacitor (34), and a rectified voltage vrec of an ac voltage vin are introduced, a virtual dc link voltage vdc in an inverter (6) is expressed by dc•vc+dr•vrec. the discharge duty dc is a time ratio of continuity of a switch (41). the rectifying duty dr has a value obtained by subtracting the discharge duty dc and a zero voltage duty dz from 1. the zero voltage duty dz is a time ratio for the inverter (6) to adopt a zero voltage vector regardless of a magnitude of a voltage to be output from the inverter (6). the capacitor (34) is charged in the boost chopper (3) at a part of a period during which the virtual dc link voltage vdc is larger than the rectified voltage vrec. ________________________________________________________________________ resumo patente de invenção: "dispositivo de conversão de potência ca direta". trata-se de um dispositivo de conversão de potência ca direta que adota uma câmara de elevador, em que a corrente-pico que flui através de um indutor que a câmara de elevador tem, é reduzida. quando um serviço de retificação (dr), um serviço de descarga (dc), a tensão (vc) ao longo de um capacitor (34) e a tensão de retificação (vrec) de uma tensão de ca (vin) são introduzidos, a tensão de enlace de cc virtual (vdc) em um inversor (6) é representada por dc•vc+dr•vrec. o serviço de descarga (dc) é a proporção de tempo na qual um comutador (41) está conduzindo. o serviço de retificação (dr) tem o valor da subtração do serviço de descarga (dc) e um serviço de tensão zero (dz) de 1. o serviço de tensão zero (dz) é a proporção de tempo na qual o inversor (6) está adotando um vetor de tensão zero independentemente da magnitude da tensão que o inversor (6) está emitindo. em uma parte do período durante o qual a tensão de enlace de cc virtual (vdc) é maior que a tensão retificada vrec, o carregamento do capacitor (34) é realizado na câmara de elevador (3).
