During this Vout spike condition, TL494 shut down the FET and can't control the output voltage. 1. Add energy absorption circuit (3*330uF+ 35W 100) could decrease the output spike, but the cement resistance is over 90 degree of centigrade.
Therefore, the TL494 can be tailored to the specific power transistor switches that are used to ensure that the output transistors never experience a common on time. The bias circuit for the basic function is shown in Figure 29. The dead-time control can be used for many other control signals. Figure 29. Tailored Dead Time 4.5.1 Soft Start
The following design example uses the TL494 to create a 5-V/10-A power supply. This design is based on the following parameters: The 32-V dc power source for this supply uses a 120-V input, 24-V output transformer rated at 75 VA.
The design of the TL494 employs both amplifiers in a noninverting configuration. Figure 23 shows the proper bias circuits for negative and positive output voltages. The gain control circuits, shown in Figure 11, can be integrated into the bias circuits. Figure 23. Error-Amplifier-Bias Configurations
