摘要： A push-pull generator provided for supply of a medical instrument includes at least one capacitive branch connected to ground, preferably in a switchable configuration, in parallel to at least one of its two transistors. Such a capacitive switchable branch can consist of a series connection of one capacitor and one switch. Thereby one of the two half waves of the output voltage of generator can be specifically influenced and the other one of the two half waves can be left largely uninfluenced. If switchable branches comprising capacitors are connected in parallel to both transistors, both half waves of the output voltage of the generator can be influenced independently from one another. This arrangement allows the specific influence of half oscillations of a push-pull generator that is apart therefrom symmetric, whereby the application spectrum for supply of medical instruments with treatment current is enlarged.

摘要： The present disclosure provides a current source circuit. The current source circuit includes a constant current circuit and a current supply unit. The constant current circuit includes a first MOS transistor, a second MOS transistor and a first resistor. The first MOS transistor includes a source connectable to an applying end of a fixed voltage, a drain, and a gate that is shorted with the drain. The second MOS transistor includes a threshold voltage (Vth) lower than a threshold voltage of the first MOS transistor, and includes a gate connected to the gate of the first MOS transistor. The first resistor is connected between a source of the second MOS transistor and the source of the first MOS transistor. The current supply unit is configured to supply a current to the gate of the first MOS transistor.

摘要： A power supplying circuit includes a first high-voltage switch, a first low-voltage switch, a second high-voltage switch, a second low-voltage switch, and a controller circuit. The first high-voltage switch receives a first input voltage and generates a first node voltage. The first low-voltage switch is coupled between the first high-voltage switch and an output terminal. The second high-voltage switch receives a second input voltage and generates a second node voltage. The second low-voltage switch is coupled between the second high-voltage switch and the output terminal. The controller circuit controls the first high-voltage switch, the first low-voltage switch, the second high-voltage switch, and the second low-voltage switch according to the first node voltage and the second node voltage such that an output voltage is outputted to the output terminal.

摘要： A test method for testing a solar power generation system is provided. The solar power generation system includes a DC to AC converter and a control unit. The DC to AC converter is electrically coupled between an external power grid and a solar panel. The control unit is configured to control the DC to AC converter to switch between a power generation mode and a test mode. When in the power generation mode, a photoelectric energy generated by the solar panel is provided to the external power grid via the DC to AC converter. When in the test mode, the control unit controls the DC to AC converter to generate a testing electrical energy by obtaining from the external power grid, to effect a test result of the solar panel when the testing electrical energy passes through the solar panel.

摘要： A voltage regulation system is provided. In the voltage regulation system, a frequency of a clock signal is adjusted and a pulse generator is controlled to output a pulse signal to a switch power stage circuit, to enable the switch power stage circuit to adjust an output voltage and output the adjusted output voltage to the load element. Through the aforementioned configuration, the switch power stage circuit adjusts the output voltage according to the situation of the load element, thus decreasing the power loss of the switch power stage circuit.

摘要： A method and apparatus are described for controlling the phase of an interleaved boost converter using cycle ring time. In an embodiment, a cycle controller generates a first drive signal to control switching of a first converter and a second drive signal to control switching of a second converter, the controller receives a first cycle signal from the first converter and a second cycle signal from the second converter, wherein the first cycle signal and the second cycle signal have a power phase time and a ringing phase time. The cycle controller determines a master ringing phase time of the first cycle signal and applies the master ringing phase time to the second cycle signal to determine a slave ringing phase time. The cycle controller generates the second drive signal in accordance with the slave ringing phase time.
