Vibrator (electronic)
Videos
A vibrator is an electromechanical device that takes a DC electrical supply and converts it into pulses that can be fed into a transformer. It is similar in purpose to the solid-state power inverter.

…fed into a transformer. It is similar in purpose (although greatly different in operation) to the solid-state power inverter. Before the development of switch-mode power supplies and the introduction of semiconductor devices operating off low voltage, there was a requirement to generate voltages of about 50 to 250 V DC from a…
