Abstract
The electrical apparatus (10) for transmitting electrical energy in a clocked manner or with clocked transmission of electrical energy is provided with an input (32) and also an output (34) and a docked switch (26) which is connected between the input (32) and the output (34). The apparatus (10) further has a drive unit (28) for docking the switch (26) by pulse-width modulation with a fundamental frequency at which drive pulses (38) follow one another. The pulse-width modulation can be operated by periodic clocking during in each case only one drive pulse group comprising a variable, predefinable number of successive drive pulses (38) or drive intervals and therefore at a subharmonic of the fundamental frequency, wherein the minimum permissible minimum number and the maximum permissible maximum number of drive pulses (38) or intervals in the drive pulse group are selected to the exclusion of subharmonics which lie within predefinable subfrequency bands which are below the fundamental frequency.
