A transistor-regulated multivoltage power supply has been designed to power a microwave transmitter. A battery voltage of 32 5 v is regulated, then transformed and rectified to yield outputs of 1000, 160, and 2.5 v. The outputs are adjustable over the ranges 4, 6.25 and 0, - 20 percent, respectively. The stability of the outputs for constant loads and input voltage variations of 5 v is better than 0.2, 0.625, and 1.0 percent, respectively. The power supply maintains this stability over a temperature range of -54C to 75C. Two of the output voltages are completely isolated from the input. Author
