Abstract: A converter module, including a housing and a converter body mounted within the housing. The housing and the converter body are joined to form a cooling channel. A fan is mounted in the cooling channel. An air inlet and an air outlet in communication with the cooling channel are provided on the housing. The cooling channel is distributed at two sides of the converter body. In the converter module described above, the housing and the converter body are joined to form the cooling channel, and the cooling channel at least is distributed at either side of the converter body, thus allowing a cooling airflow to cool the converter body from either side, favoring the implementation of even cooling, and increasing the cooling effect.

Abstract: A shutdown device for a photovoltaic module, an inverter, a rapid shutdown system, and a method for starting the rapid shutdown system are provided. The method is applied to the rapid shutdown system after each shutdown device in the rapid shutdown system initially starts. The shutdown device is switched into a mode of unlimited output in response to its success in initially starting. The shutdown device, in response to its failure to initially start or when being switched off, samples an electrical parameter at its output terminal in real time, determines whether the electrical parameter meets a preset starting condition, and switches itself on and operates in the mode of unlimited output when the electrical parameter already meets the preset starting condition.

Abstract: An unlocking circuit for a charging station when powered off is provided. A microcontroller unit outputs a first level signal and a second level signal when an auxiliary power supply is cut off. A first signal processing circuit receives the first level signal and converts the first level signal into a first control signal for unlocking an electronic lock. A second signal processing circuit receives the second level signal and converts the second level signal into a second control signal including information about action effectiveness of the electronic lock. An action execution circuit receives the first control signal and the second control signal, and responds to the first control signal and the second control signal to unlock the electronic lock.

Abstract: A method for controlling a photovoltaic rapid shutdown system, an inverting system, and a photovoltaic rapid shutdown system. In the photovoltaic rapid shutdown system, the inverting system determines whether the photovoltaic rapid shutdown system is to enter a safe mode, introduces fluctuations onto a direct-current bus in the photovoltaic rapid shutdown system in response to the photovoltaic rapid shutdown system being not to enter the safe mode, and otherwise does not introduce the fluctuations onto the direct-current bus. A shutdown device for a photovoltaic module determines according to an output parameter thereof whether an electrical parameter on the direct-current bus connected to the shutdown device meets a preset condition, controls itself to be turned on or maintains itself being on in response to the electrical parameter meeting the preset condition, and otherwise controls itself to be turned off or maintains itself being off.

Abstract: A charging pile, a power module, and a method for controlling the same. In response to receiving a signal of operation, samples of an input voltage of three relays corresponding to three phases, respectively, at an input of a power module are acquired to determine whether a line voltage between inputs of two of the three relays is within a predetermined voltage range. The two relays are closed to pre-charge a bus capacitor in a converting circuitry of the power module, in response to determining that the line voltage is within the predetermined voltage range. The predetermined voltage range comprises zero voltage, such that each relay can be closed when a voltage at its input is close to zero. An impulse current is decreased without help of an arc quenching device, thereby saving an internal space of the charging pile.
