Abstract
Circuits and devices are described that provide power to appliances and other devices via a power correction circuit and an LLC converter, which may for example include resonant series converters and flyback converters. The circuits and devices economize on board space, part size and power start up time by separately powering up the controller circuit portion prior to powering up the LLC converter.
Claims20
A power control device for an external circuit comprising:
- a control unit including a microprocessor;
- a drive unit connected to the control unit that receives a signal from a control circuit and supplies a drive signal to the external circuit;
- and
- a startup circuit that generates a drive power supply and provides current to a controller and the drive unit based on the drive power supply, wherein the startup circuit changes the current based on the signal from the controller.
1 more element
A three circuit apparatus with sequential power up capability, comprising:
- a first circuit comprising
- a microprocessor,
- a driver with a power input and one or more outputs to a PFC,
- a second circuit comprising a PFC with a power input and a power output, and
- a third circuit comprising a DC-DC converter with a power input and a power output;
- wherein
- upon application of external power to the apparatus, a first voltage increase occurs at the power input of the first circuit via a temporary connection to the external power, and then
- a second voltage increase occurs at the power output of the second circuit, and then
- a third voltage increases at the power output of the third circuit.
