Description

Technical Field

[0001] This invention relates to the field of wind turbine drive technology, and more specifically to a high-voltage generator for an ion wind turbine. Background Technology

[0002] Current wind turbine circuits simply use transformers as voltage boosting devices. High voltage is supplied to the transformer when needed and stopped when not, thus generating high voltage. However, this driving method in existing wind turbine circuits only meets the needs of starting and stopping high voltage, but cannot achieve control over the high voltage itself. The control method is relatively simple and cannot meet the requirements for flexibility and diversity in control methods. How to achieve high voltage control in wind turbine circuits and how to accurately display all values ​​on a screen have become urgent technical problems to be solved. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Figure 1 This is a schematic diagram illustrating the composition and working principle of the high-voltage generator for an ion fan. The high-voltage generator includes a power supply module, a motor drive module, a CPU control module, a fan module, a communication module, a high-voltage positive and negative ion generator, and an alarm detection module.

[0021] The CPU control module is connected to the communication module, receives instructions from the host computer from the communication module, and returns data to the host computer; the CPU control module sends PWM control signals to the fan module to control the fan.

[0022] The alarm detection module is connected to the high-voltage positive and negative ion generator and detects the high-voltage low-frequency 50Hz pulse output of the high-voltage positive and negative ion generator, and feeds back the detection result to the CPU control module; wherein, the alarm detection module includes an ion balance non-destructive alarm detection unit and a high-voltage isolation non-destructive alarm detection unit;

[0023] The high-voltage positive and negative ion generator is connected to the CPU control module and receives PWM signals from the CPU control module;

[0024] The CPU control module is connected to the motor drive module and sends drive control signals to the motor drive module. The motor drive module includes a constant current output control unit, a motor forward rotation control unit, and a motor reverse rotation control unit. The constant current output control unit outputs a constant current control voltage to the motor forward rotation control unit and the motor reverse rotation control unit according to the drive control signals, thereby controlling the motor to dry clean the discharge needle. The tip of the discharge needle is cleaned by rotating the brush, reducing the adhesion of dust to the tip of the discharge needle.

[0025] The control of the fan, high-voltage transformer, and vent detection is handled by a microcontroller. The fan has a 5-pin connector, including fault feedback and PWM control lines. When a fault occurs, the fault information is directly fed back to the CPU control module. High-voltage transformer detection is based on current; a decrease in current indicates transformer damage. The MCU first detects the vent switch. The fan includes forward / reverse rotation and alarm signal recognition. When an alarm occurs, the alarm information is directly fed back to the CPU control module. Upon receiving an alarm signal, the display will provide a notification, a buzzer will sound, and the ionizer will stop working. Fans are connected via RS-485 to transmit their status, such as fan speed, high-voltage value, and balance value. FPW1 and FPW2 control the fan speed adjustment.

[0026] The motor's windshield is monitored. Upon power-on, pin 10 of UF1 outputs a 50kHz high-frequency signal, inputting 24V to UM3 for frequency conversion control. The internal LC circuit changes the frequency, causing UM3 and the inductor to resonate, reducing the voltage to 5V. This reduces current and prevents the motor from burning out. UM1 controls the motor's forward rotation, while UM2 controls its reverse rotation.

[0027] Ion balance detection uses a metal detection ring to detect the amount of ions blown out. The detection ring and the front windshield switch but do not contact each other. The high-voltage transformer is T1. The discharge needle is connected to the output terminal of T1 to generate ions that pass through the detection ring. The generated ions are both positive and negative, and the output ions are relatively smooth. To prevent high-voltage loss, high-voltage isolation detection is performed. After high-voltage isolation detection, the ions pass through Q6 and Q7 for high-frequency resonance. The pulse value of the high-voltage ion balance is then collected and buffered and amplified by the internal transistor of the optocoupler. The current and pulse are amplified, and a red light illuminates when abnormal. At the same time, the ADC value is collected. Normally, it is 0V; abnormally, it is high-level, indicating high voltage and issuing an alarm signal. The detection ring works on the same principle. The detection ring is amplified by an operational amplifier and the voltage value is sent to the microcontroller, which calculates whether the bias is positive or negative.

[0028] A microcontroller is used for WiFi and LoRa communication; high-voltage detection alarm, fan detection alarm, and ion balance detection alarm are also included. A transistor is added next to the RS-485 for guidance; it will only operate normally when grounded, otherwise it will trigger an alarm.

[0030] Figure 3 This is a schematic diagram of the circuit principle of the driver board.

[0031] Figure 4 This is a control block diagram of the high-voltage generator for the ion fan.

[0032] The control method includes the following steps:

[0033] Step 1: Check if the windshield is properly closed and tight;

[0034] Step 2: Reverse the fan and clean the motor to begin cleaning the discharge needle;

[0035] Step 3: The fan rotates forward, and the cleaning motor stops working;

[0036] Step 4: High voltage output, fan continues to work.
