Abstract
A variable electrical energy stabilizer is supplied with a source having a voltage magnitude that varies to maintain a constant ratio with the pulsation frequency of the source. The variable supply is derived from a variable energy source such as a kinetic energy accumulator which is intended for feeding a telephone exchange or an electrical unit on a sealed off site. The stabilizer supplies a d.c. output current to a load having a predetermined impedance. To provide the load with continuous energy with a constant amplitude via solely passive components, the stabilizer comprises an inductive circuit having an inductance substantially equal to the quotient of the constant ratio to the amplitude of the output current. The inductance circuit has a very high impedance compared to the load impedance.
