Understanding PWM Controllers
What is a PWM Controller?
A PWM controller modulates the power supplied to devices by switching the power on and off at a high frequency. This technique allows for efficient energy management, making PWM controllers ideal for various applications, including battery charging. By adjusting the duty cycle of the signal, these controllers can effectively manage how much power is delivered to a load.
How Does PWM Charging Work?
When charging lithium batteries with a PWM controller, the device alternates between on and off states rapidly. This method allows for:
- Controlled Voltage: Ensures that the voltage supplied matches the battery’s requirements.
- Reduced Heat Generation: Minimizes energy loss and heat production during charging.
- Extended Battery Life: Properly managed charging cycles can significantly enhance the lifespan of lithium batteries.
