6 Claims

1. A power supply system for providing energy from an alternating current (AC) power source in a direct current (DC) to an electronic load, the power supply system comprising:

a. a first AC to DC converter connected to the AC power source that supplies power through a first AC to DC output to a switch controller and a microprocessor, and,

b. bidirectional switches located in a hot line and a neutral line from the AC power source, the bidirectional switches controlled by the switch controller, and,

c. a second AC to DC converter connected to the AC power source through the bidirectional switches, the second AC to DC converter having DC output lines connected to the electronic load, and,

d. the first AC to DC converter comprising:

i. a voltage divider connected across the first AC to DC output and the neutral line, and,

ii. a first switch, having an input and an output, connected through its input to the voltage divider, and,

iii. a second switch, having an input and an output, whose input is connected to the output of the first switch through a current limiting resistor, and,

iv. a storage capacitor connected through a diode to the output of the second switch, and,

v. a Zener diode, having a Zener voltage, connected between the input and output of the second switch and a shunt capacitor connected in parallel to the Zener diode thereby clamping a voltage between the input and the output of the second switch to the Zener voltage of the Zener diode, and,

vi. the first AC to DC output connected to the storage capacitor, and,

e. the second AC to DC converter comprising:

i. a second AC to DC converter voltage divider connected across one of the DC output lines and the neutral line, and,

ii. a second AC to DC converter first switch, having an input and an output, connected through its input to the second AC to DC converter voltage divider, and,

iii. a second AC to DC converter second switch, having an input and an output, whose input is connected to the output of the second AC to DC converter first switch through a current limiting resistor, and,

iv. a second AC to DC converter storage capacitor connected through a diode to the output of the second AC to DC converter second switch, and,

v. a second AC to DC converter Zener diode, having a Zener voltage, connected between the input and output of the second AC to DC converter second switch and a shunt capacitor connected in parallel to the second AC to DC converter Zener diode thereby clamping a voltage between the input and the output of the second AC to DC converter second switch to the Zener voltage of the second AC to DC converter Zener diode, and,

vi. the one of the DC output lines connected to the second AC to DC converter storage capacitor, and,

f. the microprocessor is programmed to send a signal through a control line to the switch controller to open or close the bidirectional switches thereby turning off or on DC current to the electronic load.
