This circuit will provide a very stable “Square Wave” Output Voltage. Frequency of operation is determined by a pot and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own FOR BEST RESULTS. Additional MosFets can be paralleled for higher power. It is recommended to Have [...]
The schematic for the 8 Watt driver will show you that this design is quite different from both previous ones. It uses capacitive ballasting like the 2 Watt driver, and a two-transistor saturation-limited oscillator like the 20 Watt design. But note an important difference: This circuit has a choke added in the DC supply, that [...]
The design depends on the windings ratio and the value of the car battery to produce an AC waveform of approximately 95 volts RMS. No filtering is performed on the secondary since the transformer blocks most of the sharp edges from the input waveform.
All of the devices (4013, 555, 4020, and 4049) should have their [...]
