Question : 43

Total: 65

The figure shows two buck converters connected in parallel. The common input dc voltage for the converters has a value of 100V. The converters have inductors of identical value. The load resistance is 1Ω. The capacitor voltage has negligible ripple. Both converters operate in the continuous conduction mode. The switching frequency is 1kHz, and the switch control signals are as shown. The circuit operates in the steady-state. Assuming that the converters share the load equally, the average value of ist, the current of switch S1 (in ampere) is ___________(upto 2 decimal places).
