During electric vibrator in front of the development of switch-mode power supplies and the introduction of semiconductor devices operating off low voltage, there was a request to generate voltages of about 50 to 250V DC from vehicle batteries.H&Z ENTERPRISE GROUPS vibrators known as Electromechanical components were used in inverter circuits to provide an alternating current (AC) electric power supply from a direct current (DC) source, which usually are converted to a higher voltage with a transformer, rectified, and filtered to create higher-voltage DC.The primary use for the beginning style of circuit was to operate vacuum tube radios in vehicles and locations with a 6 or 12V accumulator (battery) and no mains electricity supply such as farms.As we all know,common Vacuum tubes ususlly need cooperate under plate voltages ranging from about 45 volts to 250 volts in electronic devices such as radios. For the portable radios, hearing aids and similar equipment, B batteries were manufactured with various voltage ratings.To provide the necessary voltage for a radio from the typical 6 or 12 volt DC supply available in a car or from a farm lighting battery, it was necessary to convert the DC supply to AC and use a transformer to increase the voltage.
