Abstract
Various exemplary devices, systems, and methods for phase control heater control are provided. In general, a hair dryer includes a heater configured to heat air for output from the hair dryer. The hair dryer is configured to heat the air with the heater using phase control. The phase control is configured to control the heater to heat the air to a desired temperature (e.g., to a particular desired temperature or within a desired temperature range) while reducing periodic current draw on the hair dryer's AC input. The phase control is configured to control the heater according to predetermined phase angles in an AC power cycle. The methods, systems, and devices for phase control heater control can be used with devices other than hair dryers that use heaters for heat control, such as space heaters.
