<P>PROBLEM TO BE SOLVED: To provide a bidirectional converter which provides for general-purpose use rather than exclusive use and reduces manhours and cost related to development or the like as the whole power supply, and also to provide a generation method for the bidirectional converter. <P>SOLUTION: A programmable inverter includes a ROM area and a programmable area. The ROM area has a three phase/two phase current feedback computing element 21 common to the bidirectional converter 1 and an inverter 2, a (d)-axis current computing element 22, a (q)-axis current computing element 23, a two phase/three phase voltage-command computing element 24, a PWM controller 25 and an output-voltage/electrical-angle converter 26. The ROM area further has a frequency/electrical-angle converter 27, a speed F/B/electrical-angle converter 28, a switch 29 and a speed F/B converter 30. A programmable area configures a processing section by downloading a program from a PC 3 having a terminal integrated environment. A bidirectional converter program 52 is downloaded into the programmable area, and a DC bus voltage controller 31 and an electrical-angle synchronous controller 32 are configured, thus generating the bidirectional converter 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
