ABSTRACT:
Two AC-DC regulator circuits are disclosed which are suitable for providing a constant minimal ripple DC supply voltage in response to AC line voltages having varying peak amplitudes. Each of the regulator circuits includes a sensing and a trigger pulse circuit which operates in cooperation with a current control circuit to maintain a predetermined constant DC load supply voltage. Moreover, undesirable transient trigger signals, due to initiation or termination of the AC line voltage, are discriminated against providing circuit protection to the applicable load to be used. The regulator circuits are suitable for operation in environments that may be encountered in worldwide applications, i.e., power distributions that may vary from 90 upwards to 250 volts with frequencies of 50 hertz to 60 hertz.
