Abstract: The present invention discloses an air conditioner control device, air conditioning system, and air conditioner control method. The air conditioner control device of the present invention comprises a base and a controller. The base senses a temperature or humidity of a first environment. The controller can be optionally combined with or detached from the base. When the controller is detached from the base, the controller senses a temperature or humidity of a second environment and communicates with the base using a wireless network protocol. By doing so, the output of an air conditioner can be flexibly adjusted depending on the environment that a user is in.

Abstract: An synchronous rectifying apparatus or synchronous rectifying circuit of a soft switching power converter is provided to improve the efficiency. The integrated synchronous rectifying circuit includes: a power transistor connected from a transformer to the output of the power converter for rectifying; a controller having a latch circuit generates a drive signal to control the power transistor in response to a switching signal generated by a winding of the transformer in response to the switching of the transformer.

Furthermore, a maximum-on-time circuit provided in the controller is applied to generate a maximum-on-time signal for limiting the maximum on time of the power transistor.

Abstract: A synchronous rectifying circuit of soft switching power converter is provided to improve the efficiency. The integrated synchronous rectifier includes a power transistor connected from a transformer to the output of the power converter for rectifying. A controller having a latch circuit generates a drive signal to control the power transistor in response to a switching-current signal. A current transformer generates the switching-current signal in response to the switching current of the transformer. The controller turns off the power transistor when the switching-current signal is lower than a second threshold. The power transistor is turned on once the switching-current signal is higher than a first threshold. Furthermore, a pulse-width detection circuit generates a pulse signal coupled to disable the drive signal and turn off the power transistor.
