ABSTRACT:
An exponential multiplication power supply is described which is comprised of a plurality of stages each having the ability to store energy and each having a plurality of states, including at least a store state and a stack state. The plurality of stages are arranged in a network such that an input stage in the network is connected to receive a voltage from an external power source and all subsequent stages are connected to at least one other stage for receiving voltage from and through the other stages. A control mechanism is attached to the network stages and operates to place these stages in a repeating sequence of states such that at least one of the stages receives a voltage which is the sum of the voltages stored in at least two other stages. When a stage is receiving voltage or holding voltage it is said to be in the store state, and when a stage is combined with other stages to present an increased voltage, it is said to be placed in the stack state. This exponential voltage multiplication power supply is applied to the production of high voltage for exciting electroluminescent panels. The application of this power supply includes compensation circuitry to vary the excitation in response to varying characteristics of the electroluminescent panel.
