Title: Controller for pwm inverter
Inventor: MAEKAWA KATSU
IPC: H02M7/48
Filed: 1982-05-10
Abstract: PURPOSE:To reduce a shock when switching a pulse repetition rate by automatically switching divided pulse repetition rate in response to the operating frequency by switching it via the pulse width due to the prescribed predicted value at the switching time. CONSTITUTION:A voltage which is applied from a frequency setter 1 is converted via a V/F converter 2 to the pulse train of the operating frequency. This pulse train is applied to n-adic counter 3, the output of which is applied to a period measuring circuit 4, the output of which is then applied to a pulse repetition rate switching controller 7. The controller 7 automatically switches the devided pulse repetition rate in response to the operating frequency. The rate is temporarily switched via a pulse width due to the prescribed predicted value at the switching time. An arithmetic circuit 10 produces an output to a generator controller 13 on the basis of the output of the controller 7, and a pulse is outputted from the generator 14 to an inverter.
