A three-phase active rectifier is proposed for a wind power application. The wind generator delivers threephase output at voltages from 100 V to 500 V in proportion to speed, at frequencies of βˆ— to βˆ— . The power follows the cube of the speed and will be 1 MW when the output is 500 V. The active rectifier delivers energy from the generator output into a large capacitor bank. From there, an inverter processes it for grid connection. The capacitor bank is intended to maintain a nearly fixed de voltage. β€’ Draw a circuit that meets this description. Isolation is not required. β€’ What capacitor voltage do you suggest for this converter?Page 2 of 2 β€’ What value of capacitor will keep the bus ripple below 5% peak to peak over the 100 V to 500 V stated input range? The inductors have been sized correctly for low ripple and good sinusoidal current tracking.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180Β°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in Β°r, as the water flows through the pump.
