The original purpose of the contract was to develop a total vehicle control system incorporating a high frequency power supply for both battery charging and motor field control for battery powered traffic compatible electric road vehicles. By 1982 it was realised this aim could not be realised due to suitable semiconductors not being introduced by the manufacturers as soon as anticipated. The project then took the form of the separate development of an electric vehicle controller, a DC-DC converter and an off board high frequency charger. Considerable operating experience was obtained with each of these products undergoing continuing improvements. Both the controller and the converter went through two major redesigns (Mark I and Mark II). This report describes in detail, the evolution of the three designs, the principles of operation, testing, specification and revisions, and details the major circuit innovations. The bulk of the performance and reliability testing was carried out on complete vehicles which prolonged the data gathering exercise due to vehicle failures not connected with the project components.
