The invention relates to a microwave oven and a control method thereof, wherein the method of controlling the microwave oven includes: accessing the cooking time; and setting the running time of the transformer as the first time, the second time according to the total cooking time including the previous cooking time and the input cooking time Two times, a third time, and a fourth time, where the transformer runs at high output for a first time after the sleep time, the transformer runs at low output for a second time until the end of the cook time, and the transformer runs at low output after the time it runs at high output the output operates for a third time, and the transformer operates at a high output for a fourth time after the time of operating at a low output; and, the output of the transformer is set and controlled in the order of a first time, a third time, a fourth time, and a second time .

The invention discloses a method and system for suppressing the counter electromotive force of a permanent magnet synchronous motor of an electric vehicle, and relates to the technical field of electric vehicles. If the speed is greater than the preset speed, the excitation current and torque current will be adjusted according to the voltage of the bus capacitor, and the on-off of the switching device in the three-phase bridge circuit will be controlled, so that the voltage of the bus capacitor is within the preset voltage range until the motor’s current The rotation speed is not greater than the preset rotation speed. The method and system for suppressing the back electromotive force of the permanent magnet synchronous motor of the electric vehicle in the present invention protect the bus capacitor and the switching devices in the three-phase bridge circuit from being damaged, so that the whole vehicle has enough time to use the braking system to reduce the vehicle speed Down to zero without reducing motor efficiency, overheating the motor, or increasing maintenance costs.

The invention relates to a high-power neutral electrolyte metal-air battery system and a using method thereof. The battery system comprises two or a plurality of basic cell units connected in series or in parallel, an electrolyte filtering box, a circulating pump, a control valve, an electrolyte input distributor, an electrolyte discharge manifold, a drain valve, an electrolyte overflow manifold,a control circuit, a controller, a connecting pipeline and the like. Each basic cell unit consists of a reaction box, an anode, a cathode, electrolyte, a cathode busbar and an anode busbar; and an electrolyte input port, an electrolyte discharge port and an electrolyte overflow exhaust port are formed at both sides of the reaction box.
