Claims (1)

출력측에 접속한 모오터의 입력전류를 검출하고, 그 전류치에 따라서 출력전압을 조정하는 기능을 가지는 인버터에 있어서, 상기 입력전류의 대, 소에 관계없이 일정의 전압/주파수 패턴을 출력하는 전압/주파수 설정기와 이 전압/주파수 설정기에 의해서 설정한 전압/주파수 패턴을 기준에, 상기 입력전류의 대, 소에 따라서 그 전압/주파수 패턴을 보정할 수가 있는 전압/주파수 보정기와, 이 전압/주파수 조정기가 출력하는 제1의 보정치를 출력 주파수에 관한 제2의 보정치로 보정하는 전압/보정기를 갖춘 것을 특징으로 하는 인버터.In an inverter having a function of detecting an input current of a motor connected to an output side and adjusting an output voltage according to the current value, a voltage / output for outputting a constant voltage / frequency pattern regardless of the magnitude of the input current. A voltage / frequency compensator capable of correcting the voltage / frequency pattern according to the magnitude of the input current based on a frequency setter and a voltage / frequency pattern set by the voltage / frequency setter; And a voltage / calibrator for correcting the first correction value outputted by the second correction value with respect to the output frequency. ※ 참고사항：최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
