Question

Onnected to an RL load inverter with sine PWM. The de voltage is 300 V, and each phase is

(a) What is the maximum output line-to-line RMS voltage for this inverter?

Answer 1

The maximum output line-to-line RMS voltage for this inverter connected to an RL load is approximately 519.6 V.

Step-by-step explanation:

The maximum line-to-line RMS voltage for an inverter connected to an RL load can be calculated using the formula:

VLL,RMS = VDC * sqrt(3)

where VDC is the DC voltage input to the inverter. In this case, the de voltage is given as 300 V, so:

VLL,RMS = 300 * sqrt(3)

= 300 * 1.732

= 519.6 V (approximately)
