Figure 9 below shows a single-BLT configuration capable of giving 400 W into a 3  load at
10% THD with V
CC
= 52 V. This result was obtained using the STA30X+STA50X demo
board. Note that a PWM modulator as driver is required.
Figure 9. Typical single-BTL configuration for 400 W
Figure 10. Typical quad half-bridge configuration
For more information, refer to the application note AN1994.
