MULTI LEVEL INVERTER
First Claim
1. A multilevel inverter, comprising:
- a converter unit converting an inputted AC power source to a direct current (DC) power source;
a film capacitor rectifying the DC power source converted by the converter unit;
an inverter unit converting the rectified DC power source to a three-phase current in response to a pulse width modulation (PWM) control signal and outputting the current;
a current detector detecting a current outputted from the inverter unit;
a power cell main controller generating a voltage instruction and a voltage instruction using the detected current; and
a PWM controller generating the pulse width modulation (PWM) control signal using the voltage instruction and frequency instruction.
