  P03: complementary PWM

Description:
- This module is a PWM signal generator with a frequency range of 0-100KHz, which can output a pair of complementary PWM signals with dead zones or two independently adjustable PWM signals with frequency and duty cycle. The parameters can be set and saved after power failure. Using an encoder knob to adjust output parameters, the digital tube independently displays frequency and duty cycle, and can switch output signals with one click. The frequency and duty cycle accuracy can reach up to 0.02% and 0.2% respectively.

Operation Instruction:
- Short press the knob and select the parameter to be adjusted. The selected parameter flashes, and then rotate the knob to adjust the parameter.
- Long press the knob to enter the mode selection interface, and then rotate the knob to adjust the mode. Short press the knob to confirm and enter.
- Short press the START/STOP key to turn on or off the output in the current mode. When turned off, the output is low.
- After the module is powered on, it will automatically display the model and current mode (about 2 seconds) before starting to output.
- No operation within 5 seconds, parameters are automatically saved.

Precaution:
- The dead time should be less than half of the negative pulse width of PWM1, that is, DeadT < (1/Freq * (1-Duty)/2.
- Only YK-PWM1043 has complementary PWM output and dead zone control function.
- The product is powered by DC, do not use AC power.
- Do not supply power beyond the nominal voltage range.

FAQ:
Q: What are the limitations of the dead zone time range?
A: The dead time should be less than half of the negative pulse width of PWM1, that is, DeadT < (1/Freq * (1-Duty))/2; For example, if the frequency is 2K and the duty cycle is 90%, the dead time should be less than 25uS.

Q: What will happen if the dead zone time is too large?
A: If the dead time is set too large, one of the complementary signals will have no output.

Q: What is the situation where the product is connected to a circuit without a display?
A: Check if the power supply voltage is normal and between 4-28V.

Q: Can battery power be used?
A: Sure. The module has a wide power supply voltage, and as long as the battery voltage is within the nominal power supply range of the product, it can be powered by the battery.
