Disclosed is an electrical driving and recovery system for a high frequency environment. The recovery system can be applied to drive present day direct-current or alternating-current loads for better efficiency. It has a low-voltage source coupled to a vibrator, a transformer and a bridge-type rectifier to provide a high voltage pulsating signal to a first capacitor. Where a high-voltage source is otherwise available, it may be coupled directly to a bridge-type rectifier, causing a pulsating signal to the first capacitor. The first capacitor in turn is coupled to a high voltage anode of an electrical conversion switching element tube. The switching element tube also includes a low voltage anode which is connected to a voltage source by a commutator and a switching element tube. Mounted around the high voltage anode is a charge receiving plate which is coupled to an inductive load to transmit a high voltage discharge from the switching element tube to the load. Also coupled to the…

Claims

1. An electrical conversion switching element tube comprising:

  • a closed insulative housing (50);
  • a first low-voltage anode (32) mounted internally to said housing and extending internally to an electrical discharge area (62), said first anode adapted to be connected to a voltage source external to the housing;
  • a second high-voltage anode (12) mounted internally to said housing and extending internally to said electrical discharge area (62), said second anode also being adapted to be connected to a voltage source external to the housing;
  • electrically conductive means (34b) positioned internally within said housing and extending circumferentially about said second anode while being directly exposed thereto but not conductively connected thereto but, rather, spaced therefrom for receiving an electrostatic charge from the second anode when a discharge current is triggered across said discharge area between said first and second anodes, said charge receiving electrically conductive means also being internally mounted to said housing; and
  • an output terminal (60) communicating with said charge receiving electrically conductive means, said terminal adapted to be connected to an inductive load externally of said housing.

2. An electrical conversion switching element tube as claimed in claim 1, including a resistive element (30) in series with said first anode.

3. An electrical conversion switching element tube as claimed in claim 1 wherein:

said charge receiving electrically conductive means is tubularly shaped.
4. An electrical conversion switching element tube as claimed in claim 3, including

a second tubularly shaped charge receiving electrically conductive means (34a) positioned circumferentially about said first mentioned charge receiving electrically conductive means.
