Fast, Online Simulations Shape Advanced Power Supply Architectures

Fast, Online Simulations Shape Advanced Power Supply Architectures

The task of the power system engineer grows steadily more complex. At the level of individual PCBs, semiconductor devices – microprocessors, FPGAs and the like – demand a range of discrete voltage levels, frequently at around 1 V and at currents of tens of Amps. The physics of distributing power at these levels mandates regulation as close to the point-of-load as possible: I2R losses and minute but inescapable inductances are always poised to degrade the performance of low-voltage, high-current paths that see rapid step-changes in power demand. At the other end of the power-conversion...
