<p>PURPOSE:To readily stabilize output voltages by setting the capacitor ratio of a plurality of Cockcroft-Walton type double voltage rectifiers in response to the output current. CONSTITUTION:An AC power source A is connected with the primary winding W1 of a transformer T, and the input terminals of the first - third Cockcroft- Walton type double voltage rectifiers 11-13 are connected in parallel with both ends (a) and (b) of the secondary winding W2. The outputs of the rectifiers 11-13 are supplied to loads R1-R3. In this case, when the ratio C1/C2 of the capacitor capacities C1, C2 in the rectifiers 11, 12 for outputting outputs E1, E2 is, for example, set as the equation, the outputs E1, E2 can be equalized at the voltage at no load time at load connecting time. Thus, any of the outputs E1-E3 is detected to control the input voltage Ei in response to the detection level to stabilize both the outputs E1-E3.</p> |
