  "textContent": "This application provides a converter, a converter control method, and a power adapter. The converter includes: an input DC power supply, a main power transistor, an auxiliary power transistor, a first capacitor, a transformer, and a controller. The first capacitor is connected in series to the transformer to form a series circuit. The series circuit is connected in parallel to the auxiliary power transistor. A source of the main power transistor is connected to a drain of the auxiliary power transistor. A source of the auxiliary power transistor is connected to another electrode of the input DC power supply. An input negative electrode of the input DC power supply is grounded. The controller is configured to: monitor a value of a current on the transformer to obtain a quantity of times that the value of the current on the transformer reaches a specified current threshold, and when the quantity of times that the value of the current on the transformer reaches the specified current threshold is N, control the main power transistor to be turned on, where N is a positive odd number. The converter provided in this application can reduce an energy loss of the main power transistor, to reduce an energy loss of power density without increasing an overall size of the power adapter.",
