The load for the fullbridge voltage source inverter is an RL

The load for the full-bridge voltage source inverter is an RLC series circuit with R = 5, L = 50mH, and C = 100F. The inverter frequency is f = 50 Hz, and the DC input voltage is Vs = 200 V

a-Express the instantaneous load current in Fourier series up to the 7th harmonic

b-Calculate the peak load current Im.

c-Calculate the power Po absorbed by the load the fundamental power Po1.

d-Determine the effective load angle .

Solution

Basic Inverter Concept There are basically three different inverter technologies: • Inverter with a 50 Hz transformer • Inverter without a transformer • Inverter with a high-frequency (HF) transformer Figure 1. 50 Hz Technology The applied DC voltage is converted to a 50 Hz AC voltage via a full bridge (S1...S4). This is th
