Proportional firing circuit |
摘要 |
A relay control circuit which is capable of reliably controlling the transmission of electrical power in very small time increments. Specifically, the present invention features a proportional firing circuit which will create an SCR firing signal whose pulse timing is proportional to the magnitude of a variable input signal. The control circuit varies the conduction time for the SCRs by varying the time between firing signal pulses of fixed duration.
