A regulation system for a permanent magnet generator for generating electrical power and for supplying the electrical power to a load comprises a switching circuit connected between the permanent magnet generator and the load, the switching circuit being capable of regulating the electrical power being supplied to the load and a control circuit connected to the switching circuit, the control circuit for determining the amount of electrical power being supplied by the permanent magnet generator and for controlling operation of the switching circuit to regulate the electrical power being supplied to the load.

DETAILED DESCRIPTION What is claimed is: 1.
A regulation system for a permanent magnet generator for generating electrical power and for supplying the electrical power to a load, the regulation system comprising: a switching circuit connected in parallel with the permanent magnet generator, the switching circuit configured to impose a lagging power factor on the permanent magnet generator for regulating the electrical power being supplied to the load; and a control circuit connected to the switching circuit, the control circuit for determining the amount of electrical power being supplied by the permanent magnet generator and for controlling operation of the switching circuit to regulate the electrical power being supplied to the load.
2.
The regulation system of claim 1 wherein the switching circuit includes a pair of silicon controlled rectifiers (SCR's) connected between the permanent magnet generator and the load, the SCR's being selectively activated and deactivated for reducing the electrical power being supplied to the load.
3.
The regulation system of claim 2 wherein the switching circuit further includes an inductor connected in series with the SCR's.
4.
The regulation system of claim 1 wherein the switching circuit includes a pair of SCR's connected between the permanent magnet generator and the load, the SCR's each having switching times and the switching times being controlled by the control circuit to reduce the electrical power being supplied to the load.
5.
The regulation system of claim 4 wherein the switching circuit further includes an inductor connected to the SCR's.
6.
The regulation system of claim 1 wherein the control circuit is also connected to the load for determining an amount of electrical power being supplied to the load.
7.
The regulation system of claim 1 wherein the switching circuit includes a pair of SCR's connected between the permanent magnet generator and the load, the SCR's each including a gate with each gate being connected to the control circuit for activating or deactivating each of the SCR's through each gate
