Basic Electronics Notes

Transformers Tests

A number of tests are made on transformer to determine the voltage ratio, reactance of the windings, magnetizing current, core losses, copper losses, efficiency and temperature rise etc

Diode Protection

A power diode must be protected against over-voltage, over-current and transients.

Diode Circuit Analysis & Losses

To analyze diode circuits, the state of the diode (on or off) must first be found. The diode can then be replaced by the switch equivalent circuit.
