<p><P>PROBLEM TO BE SOLVED: To stabilize the output and raise the generation efficiency by minimizing the ripple of output voltage due to the ripple of a load, in an inverter type generator. <P>SOLUTION: In the inverter generator 100 which has a converter section 12 and an inverter section 13 that converts the DC output of the converter section 12 into AC, the DC output voltage Vi of the converter section 12 is detected at real time, and when defining the change rate of Vi such thatΔVi/Δti=ΔEti, it is controlled to make the current application timing in full wave rectification advance in angle during increase of Vi (ΔEti>0), and to make the current application timing in the full wave rectification fall behind in angle during decrease of Vi (ΔEti<0). Moreover, switching frequency fc is determined from the amount of ripples of the DC output voltage Vi of the converter section 12 and its calorific value, and the switching frequency in its PWM control is determined from the inductance Li of a low-pass filter 15 connected to the output side of the inverter section 13 and its calorific value. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
