half bridge converter
Hi Everyone,
I am planning to design a 500W battery charger for my UPS system with halfbridge converter. I am new to the converter design so it took me sometime to finalise the converter topology. Have i selected the right topology for my appln?
I am planning to use a microcontroller to control the PWM switching signal to the Power switches. I need to monitor the output voltage and current and hence need to decide upon the duty cycle for the PWM switching signal to the switches.
First of all is it recommended / possible to do this high freqeuncy switching by Microcontroller or do i need to go with any dedicated swithcing ICs?
I selected this method because it would simplify my life to control the output voltage and current as per the need of the battery charging characteristic rather than go with the complex analog circuitry.
Also what is instability in this kind of converters? Will it not be possbile to avoid the instability by sensing and controlling through Microcontroller?
Thanks in Advnace.
