<p>An electronics controller (10) for controlling the power supplied to a laser operating in a pulse mode is included in a power supply of the type having a resonant DC converter (16), charging a capacitive storage means (17) with an inverter stage (18) driving the laser discharge tube (22). The current (40) supplied to the laser discharge tube (22) is monitored (24). In addition, the voltage of the capacitive storage means (17) is also measured (34). Set points for the current (42), the voltage (46), and on/off (44) are provided to the electronics controller (10) as the comparison points for the controller (10). Based upon the voltage and current detected (34,24), and the set points (42,46,44) provided, the controller (10) controls the on/off (32) of the converter and its frequency (30), and the on/off (38) of the inverter (18). <IMAGE></p> |
