Abstract
The subject application provides a portable electronic heating type device with an improved power converter topology configured for receiving a DC input voltage from the power supply and generate an AC output voltage to the heating element. The power converter is based on an inductor, a DC blocking capacitor and only one switching device. Heating power can be adjusted under a pulse-width-modulation mode, a fixed-on-time mode, a fixed-off-time mode or a frequency-modulation mode. The portable electronic heating type device has less switching loss and faster response. Therefore, it can be operated at higher frequency and more compact in size.
