10.2 Typical Applications
Figure 10-1 shows the typical application of a three-phase inverter using six ISO5851 isolated gate drivers. Three-phase inverters are used for variable-frequency drives to control the operating speed and torque of AC motors and for high power applications such as high-voltage DC (HVDC) power transmission.
The basic three-phase inverter consists of six power switches, and each switch is driven by one SO5851. The switches are driven on and off at high switching frequency with specific patterns that to converter dc bus voltage to three-phase AC voltages.
