Abstract
An electronic cigarette vaporizer that includes a heating element, a power source and an electronics module that manages the delivery of power, current or voltage to the heating element; the electronics module controls or delivers pulses of power, current or voltage to the heating element, such as PWM (pulse width modulation) with a high frequency 1-10 KHz switching frequency. The duty cycle of the PWM can be approximately 90% when heating; and 1-10% duty during a preheat; and 0% when the vaporizer is idle.
