For the output power of this amplifier can generate power up to 500watt pretty good is not it. The schematic diagram is based on the design case presented in the reference designing switching voltage regulators with the tl494 texas instruments application report. To make this power amplifier please see the circuit schematic of tl494 power amplifier below along with pcb layout design.
Due to high capacity there s an inrush limiting circuit with re1 relay contact and r2 resistor.
The tl494 ic is designed in such a way that it not only features the important circuitry needed to control a switching power supply but additionally tackles several fundamental difficulties and minimizes the need of supplemental circuit stages. To make this power amplifier please see the circuit schematic of tl494 power amplifier below along with pcb layout design. Comparator first along with elements r7 r8 r9. Relay coil and fan from an at atx pc power.
