Liquid, air, and surface treatment using high intensity broad-spectrum pulsed light and method using the same

A power supply circuit for a treatment and/or disinfection system using a high intensity broad-spectrum pulsed light comprising:

• at least one capacitor power supply to supply power to a capacitor bank;
• the capacitor bank connected to the at least one capacitor power supply and a high intensity light source, the capacitor bank comprising a plurality of capacitors connected in series and/or in parallel, wherein the capacitor bank is configured to be adjustable to adjust an amount of energy supplied to the high intensity light source;
• a trigger circuit including a trigger coil connected to the high intensity light source for triggering on the high intensity light source;
• and
• a controller to:
• receive an input data from at least one of a sensor or data source,
• control charging of the capacitor bank to power the high intensity light source at a desired voltage by controlling voltage from the at least one capacitor power supply, and
• trigger the trigger circuit to turn on the high intensity light source at the desired voltage, wherein the desired voltage is based on at least the input data to determine an amount of fluence necessary to treat contaminants using a strobe pulsed light.
