Using ECCP for Half Bridge PWM
My attempt is to use ECCP in Half Bride PWM mode and construct a dc dc convertor. It works but when I changed Programmable dead band delay (changing PWM1CON value) in order to vary pulse width for output voltage correction, more heat produced in MOSFETs. Is this is a software or hardware issue? While checking outputs from PIC after disconnecting from switching devices, the wave forms seems ok. Any ideas ?? Thank you!!
