Abstract
A power converter module is connected to an electrical power supply and is configured to generate a first voltage and a second voltage for controlling operation of a valve, where the valve includes a solenoid for affecting opening and closing of the valve. The first voltage is a boost voltage for accelerating opening of the valve. The second voltage is a holding voltage for maintaining the valve in an open state. A boost control module is configured to control supply of the first voltage to the solenoid of the valve in accordance with a first state of an opening boost control signal when a valve control signal directs opening of the valve, and is configured to control supply of the second voltage to the solenoid of the valve in accordance with a second state of the opening boost control signal when the valve control signal directs opening of the valve.
