6 kV Generation This corrected pulse (PWM COMP) is then applied to the drive PAL U7-8. Drive PAL U7 will respond by varying the duty cycle of its drive signals (HVDRVA and HVDRVB) accordingly, resulting in the actual kV (KVP MEASURED) equaling the desired kV (KVP CONTROL). KV ERROR LOOP EXAMPLE 1 Lets assume that the actual kV exceeds the desired kV so it needs to be turned down. In this case the error amp U23 detects that the actual kV (KVP MEASURED) is greater than the desired kV (KVP CONTROL) and the dc voltage output of the error amp U23-1 will decrease. This causes the trip point to the PWM comparator U34, as compared to the ramp signal (RAMP), to decrease. Because the trigger point on the ramp has decreased, the pulse out of the PWM circuit U12-5 (PWM COMPARATOR) also decreases. This shortened pulse is tracked by the drive PAL U7-8. Since the pulse width of the PWM COMP signal has decreased, drive PAL U7 decreases the duty cycle of its drive signals (HVDRVA and HVDRVB). The on-time of the Darlington driver transistors is therefore decreased resulting in less energy transferred to the high voltage tank and the actual kV decreasing to equal the desired kV. KV ERROR LOOP EXAMPLE 2 Lets assume that the actual kV is less than the desired kV so it needs to be turned up. In this case the error amp U23 detects that the actual kV (KVP MEASURED) is less than the desired kV (KVP CONTROL) and the dc voltage output of the error amp U23-1 will increase. This causes the trip point to the PWM comparator U34, as compared to the ramp signal (RAMP), to increase. Because the trigger point on the ramp has increased, the pulse out of the PWM circuit U12-5 (PWM COMP) also increases. This lengthened pulse is tracked by the drive PAL U7-8. Since the pulse width of the PWM COMP signal has increased, drive PAL U7 increases the duty cycle of its drive signals (HVDRVA and HVDRVB). The on-time of the Darlington driver transistors is therefore increased resulting in more energy transferred to the high voltage tank and the actual kV increases to equal the desired kV.
