Title: Power converter for linking of systems
Inventor: YAMAMOTO TOSHIHIKO
IPC: H02M7/12
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a power converter which can control distortions which occur accompanying the problem of an output voltage being unable to control a power source current to the shape of sine-wave due to the period (dead time) for preventing the short-circuit of arms of the positive and negative switching elements and due to delayed operation of the switching elements in the power converter called the voltage-type PWM converter and the voltage type PWM inverter linked with the systems. SOLUTION: This power converter comprises a means of estimating an output current phase of the inverter, based on the system AC power source, a means for changing a dead time compensation value based on an effective power current command, a means of automatically determining the phase width of the dead band near the current zero-cross, based on an amplitude of the current command and a dead time compensation output signal means for allotting the estimated value of the output current phase of inverter and the dead time compensation value from the phase width of the deadband width to each phase and making zero the compensation value at an area near zero-crossing. Consequently, this compensation signal is added to a modulation signal to generate a PWM signal or a PWM pulse width signal as the compensation pulse, based on this compensation signal.
