Abstract
A method for generating a high pulse voltage in an inductive load consists in periodically connecting an inductive load to the outputs of a source of high constant voltage using a first controllable switching device, periodically disconnecting and connecting a control circuit of a second controllable switching device using a first controllable switch, and also periodically supplying low voltage from an output of a source of low constant voltage to the control circuit of the second controllable switching device via a second controllable switch, thus eliminating conditions conducive to transient pulsed electromagnetic interference during the generation of a high pulse voltage in an inductive load.
Claims1
A method of generating high pulse voltage in an inductive load, the method comprising:
- providing high DC voltage and low DC voltage;
- generating a first sequence of controlling square pulses having a preset duration of pulses;
- applying the first sequence of controlling square pulses having a preset duration of pulses to a control input of a first controlled gate;
- periodically connecting an inductive load to outputs of a high DC voltage source;
- thus obtaining high pulse voltage having a preset duration of pulses in the inductive load;
- as well as
- generating a second sequence of controlling square pulses having another preset duration of pulses;
- applying the second sequence of controlling pulses to a control input of a first controlled switch;
- periodically disconnecting and connecting a control input of a second controlled gate and a load thereof by the first controlled switch;
- transforming the first sequence of controlling pulses having a preset duration of pulses into a third sequence of controlling pulses, trailing edges of the pulses of the third sequence leading trailing edges of the pulses of the first sequence by a preset value;
- and
- applying the third sequence of controlling pulses to a control input of a second controlled switch periodically applying low voltage from an output of a low DC voltage source to a control input of the second controlled gate.
