Abstract
Systems and methods are provided for a transformerless power supply configured to limit heat generation. A system includes a power supply input configured to receive power from a time-varying input voltage source. A phase control circuit is configured to generate a current control signal, where the current control signal commands power to be drawn from the power supply through an output transistor, where the current control signal commands the drawn power to have a minimum current when the time-varying input voltage is at a maximum, and where the current control signal commands the drawn power to have a maximum current when the time-varying input voltage is at a minimum. A power supply output is responsive to the output transistor, where the power supply output is configured to output power drawn from the power supply input via the output transistor, wherein the outputted power is at a consistent power level.
