I need circuit that I can use as voltage injector tool for troubleshooting electronics equipment and also it can serve as power source

You will need to define this with a lot more detail.

What's the difference between a voltage injector tool and a power supply ?

Do you need 10A and 50V at the same time ?

What kind of controls.

How accurate, how noisy, how fast ?

What kind of protection (for itself and the load).

Must it include read back of voltage and current.

Is 1, 2 or 4 quadrant working ?

How big is your budget (for design and construction).

How much of the design will you do yourself ?

What do you have for a budget? Might I suggest a commercially available power supply.

The Lambda TCR40T60 or TCR80T30 might be a good choice.

I used to make very simple speed controls for model railways. The components were a speed control potentiometer, a thyristor, a reversing switch, and a resistor. There may have been more. The pot varied the trigger position, the output looked awful. The thyristor was turned off during each cycle by the back EMF from the locomotive. It worked very well with locomotives, but no good at all with Scalextric. I used the same circuit to control the speed of a modellers' electric drill, but it was a bit jumpy at low speeds. If I remember rightly it was a bit jumpy at high speeds too, as well as medium speeds.
