Any have read Microchip UPS reference design Source code and application note
I need Help regarding SPWM and Zero Crossing Synchronization
https://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=Digital-Pure-Sine-Wave-UPS...
Can some explain alternate dead time ALTDTR value calculation
Given code and comment is from Microchip reference codes
uController dsPIC33FJ06GS101
Few parameters
ADC and PWM clock is 117.92MHz ((FRC * 16) / APSTSCLR ) = (7.37 * 16) / 1 = 117.92MHz
PWM output is complimentary with center...
I have an IGBT as given below
Rise time is 180 ns from 0 to 600V
Lets say my voltages are 250V and current 50A
will its rise time (180/600)*250 = 75 ns approx
Am I right?
This code is from a reference code by MicroChip
My question is this fraction will be converted to int
How long (datatype) will be shifted 15 bits to store value in an int?
Can some one expalin the temp1 value?
dsPIC30Fxxxxxx
MPLAB XC16
Image for reference is attached and mentioned in comments
#define Speed Q15(0.51) // Fixed Point Math Library...
These are also isolate gate drive with voltage class of 1200V

If so then why ir2110 has 500V max
and ir2113 has 600V max
https://www.infineon.com/dgdl/ir2110.pdf?fileId=5546d462533600a4015355c80333167e
Here voltage class of few component is mentioned

I am not asking for Ac Power Supply
I need something like LM7812 or and any small buck converter for PCB mount
https://www.fairchildsemi.com/datasheets/LM/LM7812.pdf
Can any one suggest a Linear (Preferred) or Non-Linear Voltage regulator for 140V to 12V and Max Current of about 5A
I want to use 140V Battery to power up 12V ICs on PCB
I want to Know what is the operating voltage class for TLP250 Mosfet Gate drive working as high side mos drive
i.e,
What is the maximum value of XX Volts in Image attached.
DataSheet: **broken link removed**
Can someone explain for phase locked loop (for synchronization purpose) for 440 Hz-500 Hz Sine Wave Tone for sound application using PIC Microcontroller
Can some one explain circuit along with Pseudo code for PIC controller say PIC16F887
