Outline of SC7 |
SC7 is the harmonic
suppression PWM converter which is used in combination with
inverter.
The Power electronics apparatus generates harmonic at power supply
side.
Therefore ,while using inverter has the advatage of energy saving
and improvement in controllability,the inverter may give a bad
influence to the electric power equipment connected to a power
supply system.
SC7 controls the input current waveform close to sinusoidal-wave by
the unique control method and solves the harmonic problems at input
power side of inverter, and improves power factor to 1. |
