Abstract (en)
[origin: US4721863A] A circuit for providing a DC isolation between a pulse generator (E) and a load (CH) of the kind comprising a primary circuit (2), a secondary circuit (4) and at least one magnetization current elimination circuit (12) on the secondary side, characterized in that it is provided on the primary side with at least one unidirectional transmission circuit (15) which causes the pulses to pass and causes the magnetization current forcibly to be dissipated through the secondary in the circuit (12) for eliminating the said magnetization current and with at least one circuit (18) for attenuating the transient phenomena due to the commutation thus protecting the pulse generator (E).
