Abstract (en)

[origin: DE19732766A1] According to the invention, sensors which require a high voltage supply and require little current at least for temporary periods are supplied by an blocking oscillator with a high degree of efficiency. The efficiency of said blocking oscillator is due to the low inverse current of the rectifier, the blockage recovery time being short at the same time, the low consumption of the controlling system, and economical and therefore inexpensive voltage measurement. In particular, batteries with an especially long life can be used.
