In reality the current isn't multiplied, but with a high frequency PWM, some capacitors (see below) and a slow current meter you measure the average current from the battery rather than the pulsed current.

Could this be elaborated upon?
I understand that the average voltage would be 50V, and therefore your current must increase to have the same power transmitted as was taken. I don't understand how the current increases though. From my basic understanding of electronics, you apply X voltage to Y resistance and you get Z current (ohms law). The resistance of the load isn't changing and the voltage is actually going down. How does current increase?
