The switch power source comprises a first rectification unit (101), a switch unit (102), a transformer (103), a second rectification unit (104), a sampling unit (106) and a control unit (107), wherein the control unit (107) outputs a control signal to the switch unit (102) and adjusts a voltage of a first pulse waveform according to a voltage sampling value and/or a current sampling value sampled by the sampling unit (106) to obtain a primary sampling voltage, and adjusts a duty ratio of the control signal according to the primary sampling voltage, the voltage sampling value and/or the current sampling value, so that a voltage of a third pulse waveform satisfies a charging requirement. The switch power source can make an output voltage and current waveform change along with an input voltage and current waveform, so that a good power factor can be obtained. Moreover, when the switch power source is applied to the power adapter (1), a voltage of an output pulse waveform can be directly loaded to a battery of the terminal (2), so that miniaturization and low costs of the power adapter (1) can be realized.

摘要： In a charging method of controlling output voltages, a controller acquires first mapping relation that is a one-to-one mapping relation between at least two adjustment strategies and at least two duty cycles. Each of the adjustment strategies comprises indication information of an adjustment direction of an output voltage of a power converter. The controller determines a first adjustment strategy. The controller generates a pulse width modulation (PWM) signal based on the first adjustment strategy and the first mapping relation. The duty cycle of the PWM signal is one of the at least two duty cycles indicated by the first mapping relation and corresponds to the first adjustment strategy. The controller transmits the PWM signal such that the adjustment direction of the output voltage of the power converter corresponds to the first adjustment strategy.
