Title:
CONTROLLER FOR INVERTER
Document Type and Number:
Japanese Patent JPH04368429
Kind Code:
A
Abstract:
PURPOSE: To obtain a controller for inverters which can be operated synchronously to the voltage phase of an AC system.
CONSTITUTION: This controller for inverters is constituted of a synchronizing signal generation circuit 46 which detects the voltage phase of an AC system for operating an inverter synchronously to an AC system and outputs a synchronous signal, pulse signal generation circuit 48 which generates a control signal for controlling the inverter in accordance with the output of the circuit 46, and a control circuit 47 of a reactive power compensating device, etc. Therefore, a controller for inverters which can be operated synchronously to the voltage phase of the AC system can be obtained.
