BULK INVERTER HAVING THE CAPACITOR BANK STACK ARCHITECTURE WHICH ENHANCES THE STABILITY OF INVERTER BY MULTIPLYING THE LIFETIME OF CAPACITOR

摘要

PURPOSE: The bulk inverter having capacitor bank stack architecture minimizes the loss due to the inverter inside generation of heat by uniformly keeping the heat-generating temperature between the capacitor supplying the direct current voltage to inverter.;CONSTITUTION: An inverter circuit part(30) comprises the phase 1 voltage generation unit(21), and the phase 2 voltage generation unit(22) and the third phase voltage generation unit(23). Each of phase 1-the third phase voltage generation units comprises the first voltage generating unit and the second voltage generation unit consisting of the switching element.;COPYRIGHT KIPO 2011
