Patent ID: 11173226

Abstract:
A balanced bipolar ionizer that generates zero or nearly-zero ozone concentration by providing a bipolar ion concentration ratio greater than 80 percent based on a high-voltage output ratio less than 80 percent over a range of electric signal inputs. A signal-conditioning element provides an excitation signal to a step-up transformer which provides an output voltage to a positive and a negative voltage multiplier which provide a positive high-voltage output greater than an absolute value of a negative high-voltage output or vice versa. The high-voltage output ratio is equal to a minimum of an absolute value of a negative and positive high-voltage output divided by a maximum of the absolute value of the negative and positive high-voltage output. The bipolar ion-concentration ratio is equal to a minimum of an absolute value of a negative-ion and positive-ion concentration divided by a maximum of the absolute value of the negative-ion and positive-ion concentration.
