Ok yes I am learning, I've found out that I can test the output power of the coils and rectifier and capacitor bank by putting in a resistor inline with the positive and negative finding the voltage it drops to and squaring that and dividing by the resistance itself then I have the power out I'm going to be using a 20ohm resistor can't wait till I get my readings but things are looking good!

so I've realized that I only have quater watt resistors instead of the 10Kohm resistors at 1/2watt can I use two 5.1k 1/4 watt in parallel will the extra 200 ohms matter too much I think not but I'm just making sure!?

could spice it but just want quick answer thanks

I did the simultation in spice and I want to use two 20Kohm 1/4 watt, in parallel,not 5.1k

I had half hour today did some soldering, not enough to get jolly about so no photos, next time!

I've swapped out the 10k resistors that were supposed to be 1/2watt and replaced with two 1/4 watt 22k in parrallel so they equal 11k at 1/2 a watt the circuit properly initializes at 10millisecond finished 40% of the soldering today in 45mins pictures soon! red is the alternating current the blue and green are the alternating signal (Hin of 1 connected to Lin of 2)(and Hin of 2 connected to Lin of 1)

Good news people, I have finished the left half bridge (left hand side of the H-bridge) completed and will be taking some photos of it on monday when I can use a camera! PROGRESS!! I know its taken ages but the efforts are becoming fruitful

I must admit, it's not my best work but the connections are made soo...

I thought someone would appreciate the circuit being reallised with the help of you guys, and to say I started from scratch learned half bridge and H-bridge the IR2110's bootstrapping mosfets and all that including spice I thought you'd be pleased to see that all the help was not in vein thats why I put pictures! to see that the job got done.

I will be using arduino nano to provide the signal do I connect the ground of the arduino chip in with the inverter?

So I have been thinking maybe theres an alternative way to get my 77volts to osccillate ie in the form of a ready made H-bridge that can support 80volts that I can buy "off the shelf" because it's proving harder than I thought it would be to design the H-bridge from two half bridges and the bootstrap circuitry and the resistors capacitors and MOSFETS diode etc. Just being lazy to be fair and I probably can work it out but if there's one ready made it might make life easier. I bought some egs002 modules a while back and it occured to me that maybe I could modify it to support 77volt DC. instead of using with its recommended 12volts
Oh!
Exploring an off-the-shelf H-bridge for a 77-volt oscillation is a smart move, especially considering the complexity of designing one from scratch. It's not about being lazy but rather finding efficient solutions. Nrega

I've built the inverter already, there are pictures on post 191!
Thanks though! And welcome to the Forum!! proves that when you have an idea instilled into your head, with persistance you can achieve! what are you up to? any projects?

so progress has been slow but I'm now programming the IR2110 pulses with arduino, and can't remember the dead time if it's 1 nano-second or micro-second but think it is micro-second could you remind me?
