Figure 4-2. FET Control Signals Timing Diagram

The CONSTANT CURRENT CIRCUIT also produces a control voltage. The outerloop current sense (OCS) is taken across the current monitoring resistor and the combined signal is amplified by the CC Monitor amplifier to give the outerloop Current-Sense Voltage, I-MON. This signal is then diverted along two paths: one terminating at the barrier strip while along the other path the signal combines with the differentiated output of the Innerloop Voltage Sense (IVS). The CC error amplifier compares this combined output with the user-set CC Program Voltage to produce the CC Control Voltage.

The Control Voltage used to regulate the unit may be derived from either the CV or CC circuit. These circuits are con- nected via a wired-OR connection to the CV or CC circuit. If the CV Control Voltage exceeds the CC Control Voltage then diode A2CR24 is reversed biased but diode A2CR11 is forward biased and the CC Circuit provides the controlling signal. Similarly when CC Control Voltage exceeds CV Control Voltage, the CV circuit provides the regulating control voltage.
