The high-power inverter generally has a three-phase power input and a three-phase power output. 12 pulses refer to the rectification method
1 The meaning of single-phase and three-phase rectification pulses
1) Single-phase half-wave rectification produces one half-wave, or pulse wave, in one AC cycle;
2) Single-phase bridge rectification produces two half-waves in a. AC cycle, or called 2 pulse waves;
3) Three-phase half-wave rectification, in an AC cycle, produces three half-waves, or called three-pulse rectification
2. Series output of the three-phase bridge rectifier
1) If two three-phase bridge rectifiers are output in series, we speak of twelve-pulse rectification;
2) If three three-phase bridge rectifiers are output in series, we talk about recovery at dix-eight pulses < /; p>
3) If four three-phase bridge rectifiers are output in series, it is called twenty-four pulse rectification;
