This application belongs to the field of wireless charging technology, specifically relating to a constant current and constant voltage wireless charging system and method based on a three-coil loosely coupled transformer, including an inverter circuit, a primary-side compensation circuit, a resonant circuit, a secondary-side compensation circuit, a rectifier circuit, and a filter capacitor; the resonant circuit has an anti-parallel coil structure, with the third coil located on the secondary side and a single coil on the primary side; its advantages are high misalignment tolerance, load-independent output, and high efficiency.

The application provides an energy storage circuit with an isolation function, which comprises a power supply, a first signal generation module, a chip and an energy storage module. The power supply outputs a first voltage, and the first signal generation module generates a first signal. Based on the first signal, the chip outputs a first driving signal. Based on a driving voltage output by the energy storage module, the chip outputs a second driving signal. The energy storage module receives the first driving signal, and based on the first driving signal, the energy storage module receives and stores the first voltage. Based on the first driving signal and the second driving signal, the energy storage module converts the first voltage into a second voltage, and the energy storage module stores the second voltage.

The present disclosure relates to a method and system for producing olefins by cracking heavy hydrocarbons, which comprises the following steps: S1, entering a gas-liquid separator for gas-liquid separation to obtain a first gas phase material and a first liquid phase material; and in the process of separation, introducing a separation aid into the gas-liquid separator to contact with the first gas phase material in countercurrent, so that the heavy components carried in the gas phase material are washed or condensed to obtain a second gas phase material; S2, making the second gas phase material enter the radiant section of a steam cracking furnace for cracking to obtain a cracking product containing olefins. The above technical solution can realize the production of olefins to a greater extent by a shorter process and smaller energy consumption.

The application discloses an integrated seven-freedom-degree humanoid robot arm, the humanoid robot arm (1) comprises an upper arm module (2) and a forearm module (3), the upper arm module (2) is connected with the forearm module (3); the upper arm module (2) comprises a shoulder joint two-freedom-degree integrated module (4), an upper arm rotation freedom degree and electric adjustment installation module (5), an upper arm main control core module (6) and an elbow joint integrated module (7); the forearm module (3) comprises a forearm wrist rotating module (27), a wrist connecting rod system, a wrist turning module and a humanoid shell. The application selects a proper motor rotor and a harmonic reducer, more reasonably and compactly arranges the drivers of the relatively key wrist joint and the shoulder joint, so that the system is more compact, and has proper joint limit angles. The application provides a layout configuration suitable for the humanoid robot arm, so that the system is more reasonable and natural in layout under the premise of ensuring that strength and torque performance are stable and reliable.
