Abstract
The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.
