Power systems and methods are disclosed herein. The systems and methods use a switching system coupled with a power source and subterranean pumps for pumping a resource from beneath a surface of earth. A first capacitor is between a first switching device and a first transformer, and stores electric energy received from the first transformer to activate the first switching device. A bias capacitor is between the first capacitor and the first switching device, and receives a bias voltage via a second transformer. The bias capacitor applies the bias voltage to the first switching device to prevent the first switching device from activating unless a combination of the voltage received by the first switching device via the first transformer and the bias voltage is at least as large as the activation voltage of the first switching device.
