This is the traditional H bridge configuration for motors. The circuit is for currents up to 500 mA, but with higher power transistors such as the TIP31 motors up to 2 A can be controlled.
This non-regulated power supply uses a single secondary winding transformer. The secondary voltage...
Using a small incandescent bulb as a regulator, this Wien bridge oscillator produces a sinusoidal...
The figure presents a configuration that can be very useful for audio equipment designers. What...
